Awesome thread. I run Ubuntu (Edgy, 6.10) at home (Macs for work) and i am so very happy with it, so much that i only ever run Windows in Parallels Desktop. I have a nice dual screen set up (x2 17") with Beryl running. I have a few other distro's but Ubuntu just seems to work for me. Its great to hear that i am not the only geek out there
Ubuntu (or Linux even) isnt for everybody, but if you get through your first X error with an xorg.conf edit and it's all (mostly) downhill from there. There is a wealth of information at
UbuntuForums.org for pretty much any scenario you may find yourself in, and the
Ubuntu wiki is an absolute bible. I am still continually amazed by how smoothly Ubuntu runs on the old Dell i was going to trash, and how I can still do everything i want on it. At no point have i ever needed to revert to a Windows machine.
