Linux user here. Most PCLinuxOS Gnome on several machines, and linux Mint 10on my netbook and 1 laptop. Most machines dual-boot with XP, but very rarely boot into it, except to make sure it's updated, usually once a month or so. Just did a base install of Ubuntu 10.04 on another laptop, and built it up with only the apps I use. Will be installing Debian 6 (Squeeze on another of the machines when i have some free time. Did it a few weeks ago, but power-supply blew, and can't be bothered right now.
Have used a variety of distros, but quite like Mandriva, Debian, and Fedora. Mostly prefer PCLinuxOS tho, has about every app I want, all in the same repo, and anything not there can be requested. Rolling-release works well, and excellent hardware and multi-media support.
I'm actually quite happy with Gnome in general, and wish the desktop devs would quit changing things for the sake of change. Gnome 3's GUI seems rather counter-intuitive, and more clicks are needed than before just to do simple tasks. I'm not a fan at this point, and won't be rushing to change to it.
