I dual booted windows (xp and 7 starter for a time with Linux Mint 9, on a 1012. I've since gotten rid of Windows altogether and Now I'm runing Linux Mint 9 with multiple desktop sessions (not an alternate OS boot). I'm running Linux Mint 9 Gnome as the main session, with Sessions for Qimo for Kids, Xubuntu, plain XFCE and linux Mint XFCE.
I find that I simply don't use the laternate sessions anywhere near as much as I use the main gnome session, so after I'm done with my hardware upgrades, I plan on reinstalling LM9 gnome as a sole OS and simply uploading the packages from the others that I wanted and were not originally installed in LM9G.
With few hardware upgrades done, this OS has transformed the 1012 from a semi usable web appliance, to a full featured, peppy, affordable and truly portable computer.
