I think it's useful to distinguish between handheld, desktop/laptop, and server operaging systems.
For handheld, Android. For desktop, many are possible. For server, probably RHEL.
Regarding MeeGo, I once ran it on an HP Mini 1000 netbook and it was flawless. It actually ran better than the "native" Windows XP as well as any other Linux based OS I threw at it.
Just mentioning it in case an HP netbook is easier for you to acquire.
