I decided to buy myself a new toy (like a lot of people surfing on the netbook 'hype') : the Asus Eee PC 900
Getting CentOS installed on the Eee PC needs more work than for a traditionnal laptop (there is not cd drive and CentOS kernel doesn't have the necessary module for the integrated nic) but it's of course doable.
I don't plan to detail all the involved steps here but just a link to the page i've created on the CentOS wiki .. It's still a draft but at least you know that work is being done for the Eee PC ... As always, ideas & comments are welcome :D
