I bought a subsidised Windows EeePC 901 and stuck Ubuntu Netbook Remix on it. Much more useable. Windows was laughably bad. It limited the number of open applications!

There was also a EeePC specific https://en.wikipedia.org/wiki/EasyPeasy which was even better.

Since then I have installed various things for amusement, including a cut down Chromebook OS and the OLPC Linux. The limit was always the tiny root partition (4GB SSD). I had some limited success joining with the second SSD (16GB) using btrfs.

I think the albeit tiny SSD was this machine's saving grace compared to HDD models, in terms of speed.
