Levi Buchanan of IGN:

If you have ever used Microsoft Surface, you know that it inches us ever closer to that Minority Report-style of control. You use fingers to slide, zoom, rotate, and select on-screen elements. It really is quite easy to manipulate on-screen stuff with Surface, with the exception of one thing: typing. It remains to be seen if Apple has developed an alternate typing scheme for the tablet. Typing on the iPhone keyboard works, but it’s not ideal. Typing on a larger-than-iPhone tablet using a virtual QWERTY keyboard would be a nightmare. But otherwise, I think Surface is an excellent jumping off point for looking at how gaming might work on the tablet.
