Thanks for the intro. More relevant to this blog, I am also a long-time Mac person (bought my first one during the first week they were available in 1984), switched to Windows about five years ago "for business reasons", and then switched back two years ago because the Mac is just a better system. I went to OSX at 10.1.
If you're new to OSX and were running a nifty Finder-replacement under 9.x, you should definitely check out SNAX from Cocoatech. It is very OSX-ish, and it much more useful than the OSX Finder. I still end up doing lots of file munging in Terminal, but I never open Finder windows any more except by accident.
