OS for minibook

I have recently bought an asus eee pc and I am looking to put a new OS on it. It comes with xandros but I would like to change it to a new one. I have the limitation of screen size, though (ram can be upgraded and I can use sd cards to boost memory). I was wondering what you guys think would be good. I have been looking at ubuntu(and offshoots of it), fedora, and freespire. Any other suggestions of good Operating systems that would work well with the minibook?

backtrack 3 beta works perfectly on eeepcs. Ive got it as an HD install on mine.

this would mostly be for surfing, typing, and all around things. I wouldn't be doin much graphic or audio work though.

<off topic> is it possible to use an external optical drive for the asus eeepc? i was just curious:radio:</off topic>

well, i heard that some people managed to install Leopard on it. http://uneasysilence.com/archive/2007/11/12654/
