The Debian-based
Ubuntu Linux was unveiled today and a preview release is available for download. Ubuntu uses Gnome 2.8, kernel 2.6.8.1, OOo 1.1.2 and comes with a text-based, but dead-easy, installation procedure. Ubuntu has disabled the root user (sudo is used, same way as OSX does it) and it endorses the "less is more" philosophy. There are still bugs on the preview release, but the team welcomes feedback via their
mailing list. Read more for an interview with team member Jeff Waugh (also of Debian and Gnome fame). Screenshots also included, and more
are here to be found.
This is definitely stretching past the topic, but have you tried the xfce desktop environment; or some of the lighter distributions like Slackware, Vector, or Arch? While I haven't tried Ubuntu yet (dialup, downloading now), judging by their philosophy and the size of the ISO, Gnome should be significantly faster there than on Mandrake.
I wouldn't suggest Libranet at this stage (some nasty package repository issues), but they're a testament to how much more responsive the big DE's can be on a lighter base system.
