Gaming on an Acer Aspire One?

I’m considering getting one for other uses, and as a cheap notebook for travel. It has a GMA 950 and 1024x600 LCD display and can be configured with XP Home, so in theory it should run a Unity game. Anyone try this?

it should be enough to play thought there are other options to check from HP,Dell and Asus for small and cheap netbooks, I´m not a big fan of Acer
