First, insight into me: I do some programming (I know VB6/VB.NET, Java, and C/C++.), and I've used all of the operating systems mentioned except OSX.

Linux (well, Ubuntu, SUSE and the like), takes a bit of getting used to how things work (For example: Packages/installing things, and the file system), however, most tasks aren't any more difficult than in Windows or the like. The issue comes when you get into some of the issues that require Terminal (like some free apps and such), then things get confusing, although if you follow directions it's not hard, just "scary".

Vista: Like XP, but shinier....and with a couple annoying problems, like the slowest file transfers I've seen, and some driver issues. Also, moving everything in the control panel around for no reason is annoying, as is having to go manually enable the real Admin account.

64-Bit: XP-64 is horrible, Vista-64, in the short time I used it, seemed fine. Support for it is still lacking though, and until it starts actually coming installed on machines, that won't change.
