When you say you needed to click to install a printer what do you mean? Didn't it just load and start when you plugged it in? Mine did. I plugged it in, the computer buzzed and clicked and whirred for a few seconds, I opened Office, made a test page, clicked print and it printed.
I never had to "set up" my printer.
As for 3D animation apps on Mac, what about Maya, I hear it's pretty good. There are quite a few of them out there.
Whilst I respect your liking of Windows I will voice my opinion that I find it to be very counterintuitive, CD's not mounting on the desktop is an annoyance of mine, as is the way XP handles burning. Because the CD doesn't mount to the desktop you have to search around for the CD folder, I'm just used to click-drag-click CD burning.
Windows handles network browsing much better, I hate having to mount each folder onto the desktop just to browse shared folders on Windows machines on the network, I did like being able to just browse them as if they were folders on my own computer without having to worry about mounting and unmounting. It would also be nice if OS X would display shared printers and devices on networked machines to save me from hunting around for them in print setup. Maybe an option to just drag the icon of the shared printer to the desktop to allow use would be a good new 10.5 feature.
I just enjoy the integrated, slick OS X experience far more than the disjointed and frustrating time I have when using Windows.
