Microsoft Surface 2

     Microsoft’s touchscreen tabletop Surface was an interesting, but unwieldy, product. Surface 2 fixes pretty much all of the first version’s issues — it no longer requires a bulky cabinet, for one — and it basically gives LCDs the power to see. Its PixelSense technology lets LCD displays recognize fingers, hands and other objects pressed directly onto the screen. And since it’s no longer bulky, Surface 2 can be wall mounted — opening up a plethora of new uses.
