Ubuntu has always been one of the few Linux distros that supported by Dell D420 straight off.
I've just updated to Lynx and apart from the improved look and feel (IMHO) it's also sorted out my one "problem" peripheral, an Orange E1752 mobile broadband dongle, which now works (with no magic chickens in sight!).
Is it going to replace my Mac or Windows boxes - well no but that's not the point.
Lynx runs well on an old(ish) laptop and is all I need when out and about, so it gets my vote.
