Very cheap notebooks

I am getting awfully interested in the awfully cheap sub-notebook segment of the OLPC, Classmate and Asus eee.  As far as I am concerned, the latter is my current choice for the Xmas season, if only because it is indeed shipping.

A couple of thoughts:

* these laptops are so limited in proc power, it seems only Linux can deliver a nice user experience on them.  OK, you can install XP but it sucks on a real laptop so how bad can it get on these toys?

* Could these machines help make 20XX the year of Linux on the desktop?

If you can read French, the ultimate eee blog is here.  This guy knows his sh*t.
