I just downloaded a live cd version of Ubuntu Linux... and i have to say i am impressed. It loaded fast for being booted off of a CD, and seemed very easy to use. I am actually considering ordering one of their free CDs (yes, you do have to pay for shipping) and doing a dual boot. Most of the apps ran fast even though they were booted from a CD. I would also like to add myself to their marketshare percentage. The only problems i had were minor. I own an eMac, and after shutting down Ubuntu, the kernal ejected the Live CD and shut down, with my CD tray open. The only problem with 10.4 once i logged back in was my mouse settings seemed a lot slower (they were reset to the slow "factory" setting). I would really suggest this distribution to those wanting to try linux, easy, no geek stuff unless you want to try it. It even had an iTunes clone that encoded with OGG vorbes.
