I have the Acer Aspire One also since Feb 2009, love it. I got it back then for $330 with the 6 cell battery (around 5+ hour battery life), back then its a good deal, now u can get pretty much the same for about $200-250. I initially had WinXP on it, worked fine, put win7Ultimate when it came out, no issues with it. I use it as my secondary PC and whenever I travel, or I'll know I'll be bored somewhere and browse the web with my Verizon MiFi card.
