I’ve just been trying out
MeeGo (Intel/Nokia) on my EeePC 901. It runs very very fast, has a lovely snappy UI… but is just a little bit too cutesy for me. They should have called it Katamari OS. Other than being just a little too simple (which will probably be a plus for tablets and in-car computers), I had a lot of trouble keeping a connection to my home WiFi OR my wired LAN. And frankly, I’m still not having a lot of fun using Chrome.

MeeGo is an open source, Linux project which brings together the Moblin project, headed up by Intel, and Maemo, by Nokia, into a single open source activity. MeeGo currently targets platforms such as netbooks/entry-level desktops, handheld computing and communications devices, in-vehicle infotainment devices, connected TVs, and media phones.
Other than the overly cutesy factor, and my personal WiFi problems, MeeGo is probably worth trying. The
MeeGo website has very simple instructions on doing a ‘byte-exact copy’ of the img file to an SD card – so you can easily try it out ‘live’ without screwing with your current OS.
Personally, I’m sticking with
Mint.
