So my parents' PC is fairly old (running Windows 7) and is about time for an upgrade. I'd love to move them onto a Mac, but I dunno if I should go with the entry level iMac or entry level Mac Mini. Any reason I should pick one over the other? Also, what's the latest on remote desktop for Mac? I'd love to be able to remotely help with tech support via a remote desktop-style solution. I used to be able to do with with my girlfriend via iChat's "share screen" feature way back in '04 but that program has been all but dead for some time. Thanks.
