oooh - you'll love it
we have an older iMac and two macbook pros right now - i love the portability of the macbook pro b/c we travel a lot - but i'm actually planning for my next mac purchase to be a nice new iMac and a much smaller macbook pro that i just use for travel. my current MBP is too big and heavy (17 inch) ...
i guess i'm one of the only ones with a time capsule

i LOVE mine! i love being able to wirelessly and automatically backup and the wireless router w/ the time capsule has actually outperformed any other other router we've ever had (we had belkins and linksys routers previously) ... i have a second EHD that i use for backups as well - b/c i get nervous w/ just one ... but the time capsule is my main backup.
i have the warranty too - it has more than paid for itself w/ my MBP

(i'm not that easy on my computers)
oh - i also really like the one-to-one service - i have gone to many workshops and individual instruction sessions and learned lots.
