Linux netbooks have not sold well at all, so this seems unlikely. Atom lets makers offer XP and Win 7 which is what most buyers want.
That has more to do with the horrible choices in distro by the linux laptop makers.
If they would just have standardized on Ubuntu they wouldn't have so many issues that where related to how terrible the default repos where and the lack of update support. I've never met anyone that actually liked Xandros, Foresight or any of the rest.
An Ubuntu based system would work fine for most, its already had an ARM port for most and if they google or youtube it there is no end to information about it.
Debian, Slackware, Fedora and Gentoo guys need to stop complaining that there shouldn't be a consumer standard linux. It makes all the sense in the world as either way you know for a fact now that the hardware is supported and that with a unified base Linux can get a real foothold thus convincing companies to port those goodies you want so much to linux.
That, and all consumer x86 linux boxes should include Wine from the WineHQ repos.
