The Argument that you can't play games on that level of IGP is quite flawed.

You can play Quake III on an atom netbook.. but apart from nostalga reasons most wouldn't want to.

However there's plenty of current games that would play well on Zactate or even Ontario level of performance, that's the difference. It's perfect for those cheap indie specials on Steam for example.. which often have less than cutting edge graphics, but fresh and fun gameplay.
