We are a linux and Mac house.
The Macs are fine but a bit boring. They will run linux ports like TexMaker and others.
Our linux distribution of choice is Ubuntu. It works.
OpenSuse, Mandrivia and Debian creeping in every once in a while.
On an Acer Aspire One I use CrunchBang Linux. Nice Fast and lite.
Still some issues with the microphone on the AAO but .. tis fixable.
The AAO is a nice system for traveling.
Wireless runs well.
