I'm thinking to buy one of these cheap chinese netbooks, they run android, ideal for university, so I won't have to carry my laptop.

I want to remove android, and install Ubuntu derivatives, Xubuntu, Lubuntu, but most probably xubuntu, Lubuntu isn't much lighter as far as I know.

Will the ARM version work? Or Linux can't be installed on such devices? what I'm looking at is more of a mobile tablet than a laptop. Knowing that Linux can't be installed on mobiles got me thinking about the possible issue.

If the problem was about the requirements, I'd install debian or build Gentoo and make the lightest weight distro ever, but I think it's not about how heavy the distro is, it's about whether linux runs on mobile like laptops or not, besides Xubuntu is pretty much as lightweight as it gets especially when using the mini CD
