Macs at home and work - and they seem to work just fine for me, even when using with a GSM phone for going online - something I used to have to do on a daily basis from all sorts of weird and wonderful places.
So far (touch wood) there's been no mission-critical crash, and I've been using the things since 1987.
I've had a couple of PCs, but never really got on with them; a computer is just a tool like any other, and I'd rather spend my time using the tool than farting around with it and wet-nursing it through a zillion incarnations.
That said, the Mac does have some drawbacks. Cussed things, really - they inspire extraordinary loyaltly bordering on the obsessive in some folk. A bit like cats.
