Yeah, I can barely function with macs -- I got it because it was cheaper than a PC with the same specs (and because I knew it would be getting heavy use, as a commuting graduate student... and that's the one thing my PC laptops have never done well with, overheating). It was working fine until... it dropped dead for no reason. Which has pretty much ruined my spring break, LOL. Luckily everything was backed up (by sheer coincidence, thank god -- I'd been having fan issues the week before and backed everything up before I brought it into the Apple store for THAT.)
LOL, yeah, I seem to be the only person I know who uses it...? But my university's webmail is a pain in the ass (it logs you out after 15 minutes, and it's a 3-step login process... the interface is actually nice though), so a desktop client is the way to go.
