Always been a mac person, but mainly used laptops. My MBP is pissing me off because it seems it spends more time in the repair shop than not, but last December, we decided to splash out and get the core i7 iMac. This thing is a thing of beauty - lovely sharp, bright display (auto-sensing brightness), silent (the passive air convection is enough so that the fans rarely kick in), and has not once crashed on me. Only reboots are for software updates where they are forced.
I think Shelly is right though, you've got to plunge in at the deep end to understand and appreciate OS X... no "ah fuck it, I'm going back to the PC for that"...
The only thing that bugs me in my setup, is if someone users their account, and then I go back into my account, for some reason, the USB bus driving the scanner has powered down so the one-touch buttons on the scanner don't work forcing me to fire up the canonscan software, which sends power back to that USB bus. Oddly it's fine on the macbook if I do the same, which tends to suggest it's an imac problem.
