Time to retire the loyal 3-year-old 20" iMac to the kids and welcome the arrival of my 24" 2.93/4850 model. 
I'd like to keep this new machine zippy fresh. I'll probably do fresh app installs rather than suck everything over from my old machine. What's the best strategy for bringing over my essential info (Mail account info, iCal events, iTunes library, iPhoto library, etc.) without bringing any old system (or app-related) cruft along with it? Is Migration Assistant good at bringing over all my user info while filtering out the system bloat I may have accumulated?
