Microsoft has unveiled the Surface 2, which sports a lighter and thinner design along with a full HD screen (the same as on the Surface Pro 2).

The camera on the Surface 2 is 5X sharper, but Microsoft is touting the enhanced front camera more for Skype calls. A new third-inch sensor with a unique lens helps you make video calls in very dim lighting. Surface 2 owners will offer free international calling and free Skype hotspot Wi-Fi for a full year.

The new Surface 2 also promises to deliver 25 percent longer battery life. Other enhancements include double the bus speed for Wi-Fi and memory. The Surface 2 also moves from USB 2.0 to USB 3.0.
