It works like a charm.
No, really. The very first thing I did was wipe the hard disk so that I could install Ubuntu (I’d considered letting windows co-exist until I turned it on for the first time and was confronted with a series of licence agreements and spywares!).
I just followed the instructions here: http://seaborne.blogspot.com/2010/07/ubuntu-on-samsung-n210.html.
I can’t believe how painless this was. The install took about 15-20 minutes in total, although apparently the next version of ubuntu will install whilst taking user details; this should cut down install time even further! (the longest time for me was picking a decent password!)
