OK, I'm a PC guy switching to mac finally this week. We're getting a 24" iMac with a 500gb internal HD and my father (a mac guy) gave me a 1tb time capsule since I finally switched... Anyway, with my PC, I keep an internal HD with all my photos on it, then a size matched external that I back everything up to (manually) as well. Now with the Mac, anything I should consider before I copy over all my shots? Right now I have about 250gb of shots I want on the mac, but they're on the external firewire HD, so I could just leave them there and start fresh on the mac... But with the mac, any reason to partition the internal HD? Anything specific I should do in setting up the time capsule? TIA, I'm sooooo stoked to finally have a mac, I've been waiting years and finally needed to upgrade.
