you know all the really coooool people use Macs!
iMac at home, G4s at the office, and titanium powerbook in the bedroom stictly to listen to sox games over MLB as I fall asleep at night - with the apple hubs and routers in this place, I have maybe $6,000 worth of equipment just so that I can lay in bed and listen to the Sox on the (internet) radio just like I did with my transistor when I was 16!
We have an iMac. Nothing special. Get Jaguar if you haven't already. It is totally worth it. Just make sure you have the latest version of 9 and the latest firmware for your machine. We didn't and it cost us.
