I'm presently exploring LM because I'm not sure I'm comfortable with the direction that Canonical is taking Ubuntu. I keep hearing about Linux Mint so I'm giving it a test drive. I've installed LM 11 in a spare partition on my laptop alongside Ubuntu 11.04. my $HOME is on a separate partition and they both seem to play well with each other (which I expected since LM 11 is derived from Ubuntu.)
I'm a long time penguinista. I've been using Ubuntu since Breezy Badger and Debian before that. In the early days I used Slackware and others. IIRC the kernel for the first Linux distro I used was 0.92. That was back in the good old days when you built your own kernel and liked it!
I was happy to see a Gnome login and find that most things on my desktop seem to work out of the box. Now I just need to figure out how to get the CPU temperature indicated in the gnome-panel.
