The first thing you’ll notice about the Chromebook 13 is that it feels like a “real” laptop. The carbon fiber exterior and magnesium alloy chassis give it a look and build quality that has more in common with ultrabooks that the typical, all plastic construction of Chromebooks. It also has the sharpest, nicest IPS screen (1920×1080 matte) this side of the Toshiba Chromebook 2. While the display is sharp and clear, the model I tested did have some noticeable light leaks on two edges. I haven’t seen other reviewers mention anything of the sort though, so it could have just been my unit.
The keyboard is backlit and well-constructed with none of the sponginess that plagues some Chromebooks. The trackpad is similarly nice and I rarely had any trouble with errant taps while typing. The port setup is typical of Chromebooks in general, with a USB 2.0 port on the right and a USB 3.0 port, HDMI port, microSD card slot, and combo headphone/mic jack on the left. A nice touch: The microSD card slot allows the card to sit flush, so you can leave it plugged in for additional storage space.
One thing that hasn’t really changed in over a year of Chromebook reviews is Chrome OS itself. Google pushes out regular updates, but it’s more or less the same it was when it launched. While I still dislike the Google-centric universe that Chrome OS lives in, I’ve come around to the actual experience of using it. Chrome OS, while limited to browser-based tasks (the list of which gets longer everyday) is more secure and much easier for most people to figure out that something like Windows 10.
Hopefully Google won’t mess up Chrome’s strong points—security, simplicity, discoverability, ease-of-use, etc—in the merger with its “other” OS, Android, which at this point feels more like a complicated way to deliver malware than an operating system anyone wants to use (yes, I use it, no, there’s nothing better yet; that doesn’t make it good though).
Dell has worked with Google to add Citrix-based virtualization for Chrome OS, which makes it moderately more “business class.” This makes it possible to access your Windows desktop remotely through Chrome. Of course you can already do this with using Chrome Remote Desktop, but the Citrix version adds some security features (SonicWall VPN for instance). How useful this is will depend on what you do for work, honestly.
Dell’s latest offering could be one of the speediest Chromebooks out there if you opt for the i5 chip and 8GB RAM. That will set you back $900 though, making it the second most expensive Chromebook out there. At the other end of the price spectrum is the Intel Celeron 3205U processor, 2GB of RAM, which will run you $399.
The model Dell sent WIRED was the next one up from the bottom, which has the same processor and hard drive but adds 2GB of RAM for a total of 4GB. This model sells for $449. Performance on this lower end machine was fine for everyday tasks, though if you do want to log in to your Windows machine and have a dozen tabs open at the same time, you should spend the money for one of the more powerful models.
Battery life may well be even more important than raw power with Chromebooks, and the Dell is hard to beat in that department. Dell claims up to 12 hours, and in my testing that’s pretty close to accurate. If you go on a Mr. Robot bender and stream hours of video you probably won’t get to 12 hours, but for everyday use—email, news reading, Web browsing, streaming music—the Dell has very impressive battery life.

First up is the computer gaming hardware market. As a player looks to one part of the screen, the image will pan across the landscape and open up a new field of vision.
Whether it catches on in the fiercely competitive gaming industry could depend on a deal struck this year between Eskilsson's company Tobii and Ubisoft, maker of blockbuster game "Assassin's Creed: Rogue".
Tracking the player's gaze, the eyes of warrior Shay Patrick Cormac look across seascapes, forts and battlefields as he hunts assassins in North America during the Seven Years War in the PC version of the game.
The success of this and other tie-ins is the biggest test yet for Tobii, which is making no revenue from supplying its technology for the deal.
The aim is to get enough players interested to lure other gaming companies for deals that would bring in revenue. So far it has a handful of other tie-ins and Eskilsson said eye-tracking will have to reach at least 30 to 50 games before it can be regarded as mainstream.
The prize is huge: Tobii's sales ambitions suggest an overall market for gaming eye-tracking sensors that could top $5 billion a year in revenue, about six times the firm's market value.
"Eye-tracking makes it possible to create a more human device," said Eskilsson at Tobii's Stockholm headquarters, his laptop slipping into standby mode after noticing that he had looked away.
"Not only by steering with your eyes, but with hands, voice and where you are looking. All put together."
SMARTPHONE HURDLES
The company faces further hurdles before it can break into the far larger smartphone market.
Fund manager Inge Heydorn at Sentat Asset Management in Stockholm compared Tobii's gaming-focused business to a hard-to-value stock option and said its sensors must become cheaper and smaller and consume less energy if they are to be used for smartphones packing far less battery power than laptops.
"They don't know if they will get power consumption down. We don't know. Nobody knows," said Heydorn, who holds no Tobii stock.
Tobii dominates the market for now - its $75 million in 2014 sales is five times that of its closest rival among about 20 eye-tracking technology firms - by selling sensors as disability aids and for behavioural studies in research.

Keeping that edge may prove a challenge now that big technology firms, some of them Tobii customers, are looking at whether to develop their own technology.
South Korean giant Samsung's latest phone reads the position of the user's face, something Eskilsson sees as a precursor to full-blown eye tracking.
Tobii's deep-pocketed backers include Swedish group Investor , with a 19 percent stake, Intel Capital and early Spotify investor Northzone, both with roughly 8 percent.
Expectations for profit growth are sky-high and Tobii's share price has almost tripled since its April listing. The company is investing about 150 million Swedish crowns ($18 million) annually to expand in PC gaming.
