Microsoft's big Surface reveal today is packed with plenty of spec bumps, but one if its most important features might be an accessory. The Surface Power Cover adds a 30 watt hour battery to the already massively improved Surface Pro's battery life. Meaning you might actually be able to make it through the day.
Battery life was a huge focus for Microsoft in general at today's announcement, given that the previous generation hovered around three hours. Not only is the internal Surface Pro battery 75 percent better, per Microsoft, it'll get a significant boost from the not too bulky cover. In all, Microsoft is promising a two and a half times improvement, which gets you close to 8 hours of real world Surface Pro usage. Not bad, especially compared to what you'd get out of a comparable ultrabook.
Microsoft also announced a Surface docking station, which comes with ample ports (three USB 2.0, one USB 3.0, Mini DisplayPort, audio in/out) and can power up to two external monitors. The Surface slides into the docking station like rye bread into a toaster.
The Type Cover has gotten an overhaul as well, shaving off a millimetre of thickness, which puts Microsoft's full keyboard Surface cover at about the same bulk as last year's touch input cover was. It's also backlit, with automatic dimming after about ten seconds of non use. For the fashion-forward, it comes in purple, pink, blue, and black.
