My Winderz (and Kubuntu capable) Acer netbook of a few years back has Atom in it, though it is the 32 bit version.
Winderz might need special memory management or other things that the Pine board does not have, though. Trying Windows 7, 64 bit might work — or it might end up in a grand choke.
Ya, it might work. Why would I want to though?
