I've been testing several distros -including Mandriva 2009- for my wife's Acer Aspire One 150. Found the best for my/her needs [color=#0000BF]Mepis[/color] (at [URL]http://www.mepis.org[/URL]), Debian Lenny based. Now it is still in final beta release, but has worked rock-solid for us. You can find more reviews and help at MepisLovers ( [URL]http://mepislovers.org/forums/index.php[/URL] ), Also you can find some tweaks at k/ubuntu forums or Debian Ones. Wifi, LEDs, Fn keys, sound, etc. works flawlessly. Hope this widens the possible choices.
