ASUS is considering to install the Linux-based Google Android OS on future Eee PCs. Google initially developed Android for cellphones (T-Mobile G1) but ASUS has allocated engineers to develop an Android-based Eee PC netbook by as early as the year end.

The EEE PC 1000 is a neat little machine. It’s a lot more expensive than the original EEE PC, but it’s still cheap for a subcompact. It ships with Xandros Linux. That’s a good distribution for people who
want an easy-to-use machine for web browsing and word processing. However, I need LaTeX and Emacs for my work, and I haven’t been able to find a good way of installing that on Xandros. Since I use Ubuntu
Linux everywhere else, I’m trying to install it.

I've used this site to install slackware on my asus U5F.
I'd rate it at intermediate, not beginner user level if you intend to follow this tutorial.
