I own an iMac right now that I basicially bought to see if I could make the transition. Overall, yes I can. There are a few quirks in the interface, but I find myself less put off then trying to work only in OS 9. Add to that a Unix layer right under my feet that will give me tons of things to do, and I'm happy. I've talked to so many Mac people who don't like OS X due to "issues" over 9, but I don't have that hindsight to worry about. I don't overly like Apple for some of their decisions over the years, but I despise MS even more. I haven't directly paid for an MS product (beyond one game) ever, and I figure ridding myself of the MS world as much as possible is a good thing. While I could go the Linux route, the interfaces to it still seem too clunky to me.
