I dunno what the reviews say, but from personal experience I know the keyboard is tiny and hard to use, the screen is an odd shape so it uses weird resolutions making it hard to play games that don't stretch to fit the screen, and because of the small screen I think it's kinda hard to read/see things sometimes.
This is the one I got for my wife:
Newegg.com - Acer Aspire One AOD150-1165 Blue Intel Atom N270(1.60GHz) 10.1" WSVGA 1GB Memory 160GB HDD Netbook - Netbooks
I've only used it a few times, I'm not especially fond of it but she likes it a lot. They're great on battery life.
