Acer Aspire One 522
When I first saw this Aspire One advertised for 230 Swiss Francs (about £160), I thought it must have been some kind of mistake. I went and looked at it in the shop, and I still thought it was a mistake - it looked like a pretty nice little netbook for such a low price.
The Aspire One comes preloaded with Windows 7 Stupor Edition. That's unfortunate, not only because it is Windows, but because it is "Lobotomized" Windows.
Load just about any current version of Linux on this little gem, though, and it really starts to shine. So far I have loaded Linux Mint 11 (and 12RC), Linux Mint Debian 201109 Gnome, openSuSE 11.4 (and 12.1 RC2), Ubuntu 11.10, Fedora 16, PCLinuxOS 2011.09 and Debian GNU/Linux 6.0.3.
