All 2014 Prius hybrids to roll with plug-in and 2011 pricing, Hoitz and Gamble rejoice

Hybrid cars are sleek, efficient, and even occasionally sexy. Cheap they are not, however, though Toyota hopes to stir up the market in 2014, with affordable plug-in models that also boast much-improved mileage ratings. That year's Prii will ship standard with plug-in, and will quietly conquer at least 90 highway miles per gallon (compared to about 50 mpg for current models), according to Autoblog. The 2014 Prius will also be priced comparably to current non-plug-in models -- around $25,000 -- assuming Toyota can successfully reduce the cost of batteries and other key components. We can only hope that fuel prices aren't any higher three years from now, but even if they are, at least you'll still be able to afford to commute in something larger than a Vespa.

Google to offer $20-a-month 'student package' for a Chrome laptop?

Just as we're wrapping up day one of Google I/O 2011, Forbes received an interesting piece of information regarding Chrome OS. According to an unnamed senior Google executive, tomorrow's keynote will see the launch of a Chrome laptop sold as an attractive $20-per-month "student package." If true, this will make a compelling option for laptop-seeking students bounded by a limited budget (booze before books, right?), and Forbes speculates that a similar enterprise offering will follow soon -- makes sense considering Google's already cosying up to businesses with its $50-a-year Google Apps suite. Anyhow, all will be unveiled soon enough -- keep an eye out for our Google I/O day 2 liveblog tomorrow for the full monty.

RoboDynamics Luna: the 5-foot tall personal robotic platform (updated)

It's a new era for personal robotics. Meet Luna, the fully-programmable robot companion platform that will ship this year. As a platform, RoboDynamics -- a Santa Monica-based company previously grounded in telepresence -- is trying to position Luna as the 5-foot tall "beige box" of modern robotics. She comes with her own one-click Luna App Store, eight "Luna Expansion Ports" (think 12/5 volt USB for robots), and Luna CloudNet where third-parties can sell additional functionality like face recognition to app developers. The robot ships with a number of personality packs and features an 8-inch touchscreen, two cameras, wireless connectivity, a three-mic array, and a variety of sensors. Oh, and she's portable. Remember, Luna's not a prototype, but a real working robot that you can actually take home for the price of an entry-level fully-loaded laptop.

Update: While $1,000 is the ultimate target price, the initial batch of limited edition Luna robots will ship in Q4 for $3,000. General availability will begin in the second half of 2012 with final pricing coming later this year.

Sharp Aquos Phone SH-12C has 3D cameras, qHD resolution, Gingerbread filling

The HTC EVO 3D and LG Optimus 3D just got themselves a new buddy in the three-dee picture-taking arena in the shape of Sharp's Aquos Phone SH-12C. We know, that name just rolls off the tongue. What's remarkable about the 12C is that the dual cameras on its back go all the way up to 8 megapixels (to the EVO 3D's 5), which will be creating quite the tasty workload for the 1.4GHz Qualcomm MSM8255 chip contained within. A qHD (540 x 960) screen resolution also keeps up with HTC's latest, though the 4.2-inch, 3D-capable display on the Aquos offers more pixel density and less in absolute real estate. Android 2.3, replete with some evident customizations, will serve as the OS, and 720p video recording in 3D will also be available when Sharp launches the 12C in Japan on May 20th. Rest of the world? Well, we can dream about it right now.

Charlotte Motor Speedway, Panasonic flip the switch on the world's largest HD screen

Charlotte Motor Speedway and Panasonic held an event yesterday to celebrate the completion of the new world's largest HD screen, which measures at 16,000 square feet (200 feet wide and 80 feet tall). Of course, the only natural thing to do when face with a screen this size is to play videogames on it, and CMS got very meta by bringing out NASCAR driver and simulation racing fan Dale Earnhardt Jr. to turn a few laps on the track in iRacing on the brand new display. The 720p display, located on the backstretch, is big enough for fans seated along the front stretch of the track between turn four and turn one to have a clear view of replays, standings and stats all the way across the track. Its official debut will take place May 21st during the NASCAR Sprint All-Star Race and will also take a turn as a massive HDTV airing clips of Top Gear USA during a History Channel sponsored race the week after. You can see the videogame rig, screen and ceremonial oversized remote above while video of them actually playing is available at the source link.

Nexus S 4G on sale today: $200 at Sprint, $150 at Best Buy

It looks the same, it works the same, and though it's three-tenths of a millimeter thicker than the original, Sprint's Nexus S 4G has one major difference: it sports a WiMAX radio. Today, the freshest Gingerbread smartphone goes on sale, just as planned, bringing the same 4-inch curved Super AMOLED screen, 1GHz Hummingbird chip and NFC capabilities your T-Mobile counterparts have enjoyed for months plus the promise of Google Talk video chat. Find it for $200 on-contract directly at Sprint, or shave $50 off the sticker price if you're a brand-new customer by trying Best Buy instead.

HP unveils the Pavilion dv4, Envy 14 with Sandy Bridge, and a redesigned Mini 210

With a Sandy Bridge refresh, a new 14-inch mainstream laptop, and a redesigned netbook, HP's latest crop of consumer systems offers a little something for everyone. First up, there's the 14-inch Pavilion dv4 (not to be confused with the metal-clad dm4), which bears the same Imprint finish and CoolSense technology as its siblings and ushers in a striking cobalt blue color option, as you can see in the photo above. Look for it on May 18 with a starting price of $600.

Then there's the revamped Mini 210, which swaps last year's not-too-glossy plastic lid for candy-colored lids, and adds a seamless touchpad, edge-to-edge 10.1-inch display, and a flush six-cell battery promising up to 8.8 hours of battery life -- an upgrade over last year's standard four-cell. Spec-wise, nothing has changed from the current 210, except for the addition of Beats Audio, something you'll find across HP's notebook lineup. It'll be available on June 15 and cost $300 for the charcoal version -- alas, you'll have to pony up $330 for one of the punchier colors. For now, be sure to check out our video hands-on.

Lastly, HP did the predictable and refreshed the high-end Envy 14 with Sandy Bridge CPU options and USB 3.0. It also promises an improved touch experience -- something we bemoaned in our review last year -- with a trackpad that uses optical sensors to analyze your multitouch gestures. That will go on sale June 15 for $1,000 and up.

HP intros the ProBook 5330m, EliteBook 2560p, and EliteBook 2760p tablet

After announcing a trio of consumer laptops, you didn't think HP had forgotten about its business line, did you? The company also trotted out three lightweight models for the corporate set, including the 12.1-inch EliteBook 2760p convertible tablet, which has been rearing its head around the FCC as of late. Although it's an update to the current-generation 2740p, it sticks with its tried-and-true metal design. But -- surprise, surprise -- it steps up to Sandy Bridge Core i5 and Core i7 CPU options, promises 5.5 hours of battery life with the standard six-cell, and will be one of several models compatible with HP's newly minted (optional) prepaid data service, DataPass. Is this the Windows 7 tablet you've been looking for? It's on sale now starting at $1,500 -- stylus included.

Next up is the EliteBook 2560p laptop, an update to the 12.1-inch 2540p. This one, too, has a tough aluminum-and-magnesium-alloy build, but it gets the good ol' Sandy Bridge treatment and also shifts to a 12.5-inch display -- a screen size that's rarely stretched to 16:9 proportions. And, HP claims it's the only laptop of its size with a built-in optical drive, if sacrificing optical discs isn't a compromise you're willing to make. Look for it on May 23 with a starting price of $1,100.

Lastly, there's the ProBook 5330m, a 13.3-incher that's trying hard to win over Generation Y-types just dipping their toes into the workforce... and who will call in sick if their work machines aren't trendy, or something. In addition to a dual-tone aluminum chassis, it plays cool with a backlit keyboard, Sandy Bridge Core i3 and i5 CPU options, and Beats Audio -- a first for an HP business system. On the inside, meanwhile, it offers TPM circuitry and optional Intel vPro processors -- perks for the IT managers likely to buy these in bulk. These are on sale now, starting at $800.

Samsung's 75-inch D9500 3D TV announced for Korea, doubles as wind shield

3D is best served on a large plate, which is why Samsung's latest HDTV got us all dribbling over our TV munchies. This 75-inch platter, dubbed D9500, has stolen the short-lived crown off LG's 72-inch LZ9700 to become the world's largest LED-backlit 3D LCD HDTV, and obviously Samsung's still staying faithful to its active shutter 3D technology following its recent price drop on its glasses. The 240Hz display will also come with the usual Smart TV features, garnished by a QWERTY flip remote for your web-browsing and SNS needs on that large screen. Oddly enough, only an ex-factory price of a whooping ₩19,000,000 ($17,600) is quoted here, so customers will have to pay a bit more than that during the pre-sales at the end of the month. Alternatively, you can hold off your shopping spree until Samsung pushes out its 70-inch "Ultra Definition" 3DTV.

Apple brand valued at $153 billion, scoots ahead of Google for first place

What is the world's most valuable consumer-facing brand? If you'd asked the guys behind the BrandZ survey at any point over the last four years, they'd have told you "Google," but in 2011 their answer has changed. Apple is now the hottest property in terms of consumer goodwill, earning an estimated valuation of $153.3 billion and leading a pack that includes the likes of Coca-Cola, BMW, HSBC, and Disney. The tech sector had a very strong year as a whole, with Facebook's brand improving in value by a staggering 246 percent (to $19.1b) and Amazon becoming the world's most valuable retailer (at $37.6b) in spite of having no actual stores. Sadly, there were some downers too, as Nintendo lost 37 percent of its brand worth over the past year, Nokia dropped by 28 percent, and the BlackBerry marque was considered 20 percent less awesome than before.

Brammo delays flagship Empulse electric motobike to 2012, teases new transmission tech

Bad news for Brammo's electric bikers: according to Asphalt and Rubber, word has it that the company's flagship Empulse motorbike will now be delayed to 2012, citing CEO Craig Bramscher's decision to integrate a certain new technology before launch. What could this be? Well, the site speculates that this has something to do with the six-speed Integrated Electric Transmission (IET) that Brammo recently licensed from Italian firm S.M.R.E., and this technology's already featured on the company's Engage and Encite dirt bikes announced last week. That said, there's also a rumor that Brammo didn't reach its pre-order goal of 1,000 units, which would certainly make sense for the company to delay the launch to pimp up its 100mph ride. We asked the Stig for a comment, and he wasn't impressed.

ASUS Sabertooth P67 motherboard sheds its skin, feels better without it

There's no denying the ASUS Sabertooth P67 motherboard looks fantastic, and The Tech Report didn't spare praise for its military-grade components or five-year warranty in a recent review, but the publication also reports that the standout feature -- that component-cooling "Tactical Jacket" -- may hurt more than it helps. The plastic shroud has been re-dubbed "Thermal Armor" since our last run-in, but that doesn't change the result: ASUS doesn't ship the primo slab with a dedicated cooling fan, so component temperatures can actually go up ten degrees Celsius when wearing the shroud with a system under heavy load. Of course, cooling depends on a number of factors, but we were hoping the Sabertooth's unique coat would be a positive one. Back to the drawing board.

Fujitsu's Stylistic Q550 business slate up for US pre-orders, starting at $729

We're still not sure what's stylistic about Smart Card readers, fingerprint scanners and TPM modules, but you won't find them in many slates, so if you've been considering the Fujitsu Q550 -- which has one of each -- today's your lucky day. The Oak Trail-powered Windows 7 tablet with a 10.1-inch, 1280 x 800 IPS screen is ready for US pre-orders today, with $729 bringing you the base model with a 30GB solid state drive and a two-cell rechargeable battery. $849 upgrades the slate to 62GB of storage and four cells worth of swappable Lithium-ion joy, while both sport front and rear cameras, HDMI out, a bootable USB 2.0 port, a full-size SD slot and dual-band 802.11 a/b/g/n WiFi. Let's just hope the UI is a tad more optimized than last time.

CTA's translucent Kinect steering wheel, for when you absolutely, positively must see the road

Steering wheels: sure, they're fun and functional, but why do they have to be so opaque? It's like you can't see through them at all! Our friends at CTA Digital -- purveyors of such fine gaming peripherals as the Wii bowling ball and the Nintendo DS/DSi Puppet Pouch -- are thinking outside that particular box with the aptly named Transparent Steering Wheel. Looking like something pulled from the wreckage of Wonder Woman's invisible plane, the TSW is nothing more than a transparent (well, translucent if we're being nitpicky) piece of plastic shaped like a steering wheel, which promises more precise driving on the Kinect racetrack. The company's apparently still perfecting the clear-plastic technology, which will ship June 5th, setting you back $12.99.

Hyperkin 3DS Powerplus covers your handheld in battery-extending goodness

Nintendo 3DS users will soon have another way to extend their system's notoriously limited battery life, thanks to Hyperkin's new 3DS Powerplus. Slated for release this summer, the 2.2-ounce accessory slips on to the back of the console without obstructing the 3DS' cartridge port, SD card and game controls, while adding an extra 1800mAh to the device's standard 1300mAh battery. The Powerplus also features an enhanced grip, as well as an LED indicator that can give you an idea of how much gas you've got left in the tank. Hyperkin says its $19.99 appurtenance will more than double your 3DS' battery life, but, as we learned from Nyko, seeing is believing. Head past the break for an extra image of the Powerplus, along with a full PR.

WiMAX sleeve brings 4G speeds to the iPhone 4 in South Korea

This is exactly how we humans got out of the trees five million years ago. We spot a problem, like the iPhone 4's lack of 4G data, and we solve it. In fact, Korean Telecom's new Egg sleeve not only brings WiMAX to the iPhone 4 but also incorporates an extra battery to allow five hours of 4G surfing. It could make bipedalism slightly uncomfortable however, by bulking your pocket out with 2.4 ounces (68g) in added weight plus a third of an inch (8mm) in extra thickness. Primates outside of South Korea can't buy the ₩129,800 ($120) Egg right now, but problem-solving minds can always use 4G mobile hotspots instead -- like the Sprint Overdrive or Verizon's new LTE-based MiFi. That's why we're the jungle VIP.

NASA concludes Gravity Probe B space-time experiment, proves Einstein really was a genius

Well, it looks like Einstein knew what he was talking about, after all. Earlier this week, researchers at NASA and Stanford released the findings from their six-year Gravity Probe B (GP-B) mission, launched to test Einstein's general theory of relativity. To do so, engineers strapped the GP-B satellite with four ultra-precise gyroscopes to measure two pillars of the theory: the geodetic effect (the bending of space and time around a gravitational body) and frame dragging (the extent to which rotating bodies drag space and time with them as they spin on their axes). As they circled the Earth in polar orbit, the GP-B's gyroscopes were pointed squarely at the IM Pegasi guide star, while engineers observed their behavior. In the universe outlined by Einstein's theories, space and time are interwoven to create a four-dimensional web, atop which the Earth and other planetary bodies sit. The Earth's mass, he argued, creates a vortex in this web, implying that all objects orbiting the planet would follow the general curvature of this dimple. If the Earth's gravity had no effect on space and time, then, the position of NASA's gyroscopes would have remained unchanged throughout the orbit. Ultimately, though, researchers noticed small, but quantifiable changes in their spin as they made their way around the globe -- changes that corroborated Einstein's theory. Francis Everitt, a Stanford physicist and principal investigator for the mission, poetically explained the significance of the findings, in a statement:

"Imagine the Earth as if it were immersed in honey. As the planet rotated its axis and orbited the Sun, the honey around it would warp and swirl, and it's the same with space and time. GP-B confirmed two of the most profound predictions of Einstein's universe, having far-reaching implications across astrophysics research. Likewise, the decades of technological innovation behind the mission will have a lasting legacy on Earth and in space."

The GP-B mission was originally conceived more than 50 years ago, when the technology required to realize the experiment still didn't exist. In fact, the experiment didn't actually get off the ground until 2004, when the satellite was launched into orbit 400 miles above Earth. After spending just one year collecting data (and an impressive five years analyzing the information), NASA has finally confirmed something we always quietly suspected: Einstein was smart. Head past the break to see a more in-depth diagram of how the GP-B gathered its data.

Jaguar will actually build million-dollar C-X75 hybrid supercar in 2013

You know how we said that 780bhp electric pipe dream Jaguar had last year wasn't going to be anything more than a concept? Well, we were wrong. Sort of. You see, the British automaker has just announced its intention to produce a limited run of 250 C-X75 supercars in partnership with Formula 1 team Williams, however the retail model will eschew the craziest aspect of the original design -- the twin turbine engines at the back. Those will be replaced with a four-cylinder, turbocharged petrol engine, which will aid the four electric motors (one attached to each wheel). Don't worry, though, this tweak has actually made the C-X75 accelerate even faster, as it's now rated to go from 0 to 60mph in under three seconds. 2013 is when the earliest production of this road-faring beast is expected to commence, with prices starting at £700,000 ($1.15 million), and there's even a glimmer of hope that a version with the gas turbines will also be built at some point down the line. Crazy, just crazy. Check the C-X75 out on video after the break, where Jay Leno gives you a tour around its dramatic design.

Google and Sprint respond to Google Voice integration issues

You may recall from yesterday that early adopters were having a variety of issues after activating (or attempting to activate) Sprint's new Google Voice integration feature. Well, a full day has passed, and we've had several calls with GV lead Vincent Paquet as well as Brian Smith, Sprint's director of product development. Both executives have said that their respective companies have been hard at work on resolutions to each of the issues we outlined Thursday night, and some customers we spoke to yesterday are now back online. Jump past the break for a quick summary of what's been fixed, and what remains on the to-do list.

Our primary concern yesterday was a voicemail security bug that inadvertently granted management-level access to people that one user called from the Google Voice web app. Google is not commenting on this vulnerability, but has confirmed that it's not a threat today. The second issue was that some GV customers who were up and running with Sprint integration suddenly found themselves unable to use the service. This issue has been pegged to the removal of an accounting code -- GGLVOICE -- that some Sprint reps have accidentally removed. The carrier is working to prevent this from occurring in the future, and those already affected should soon be able to call in for support. Next up, some international calls were being processed through Sprint, rather than through GV, even after users activated their integration. This has been tied to the accidental removal of the same accounting code, and Google has offered to reimburse affected individuals (see the update on yesterday's post for full details).

Finally, many users -- notably those on personal accounts with corporate discounts -- have been unable to activate GV integration. Sprint has promised a mid-May resolution, and we'll certainly keep you updated. Users with these issues are still being instructed to share their concerns on the Google Voice Forum, which as of now is finally getting the attention it needs. You can also post a comment below, as both companies have been monitoring here, too. Things are looking much better today than they were yesterday, but our position remains unchanged: Unless you've already activated Sprint/Google Voice integration, please stand by until both companies have had a chance to work out these (very significant) kinks. You've been able to hold out this long -- what's another few weeks?

Update: Sprint customers on corporate and government accounts (paid for by your employer) are currently not eligible for integration. Eventually, Sprint will enable integration for some of these companies on a case-by-case basis.

Space Adventures will shoot you (and your ego) to the moon for $150 million

Y'know, there are only so many pristine beaches and spectacular slopes one can see before terrestrial tourism becomes blasé. That's why Space Adventures -- who lets folks vacay in space via suborbital jaunts -- is offering to shoot you to the moon during your next work sabbatical. Amateur astronauts won't actually land on the lunar surface, of course, but their Soyuz spacecraft will get within 62 miles of it. To indulge in your lunar fantasy, it'll only cost you 150 million bucks, or roughly the GDP of a [insert small island nation here]. One of the two seats is already taken, but the company needs another would-be moon man or lunar lady before the trip's a go. The only thing stopping us (and everyone we know) from signing up is an empty bank account -- does Fastweb do spaceflight scholarships?
