Doesn't work on XP and they kept that news secret - not impressed in the slightest :(
Not quite sure why it's Windows 7 only, but you'll probably find more and more companies drop support for XP as 08/04/2014 approaches.
Tried this out with Angry birds on an 65" CleverTouch screen. Just like having a massive android tablet. Also NinjaFruit works well on the massive screen although is a good workout stretching on the big screen.
We are currently on the lookout for educational apps that work too.
