They're cool. They work. They let me get my work done without fuss. Hell, even OS9 was really cool IMHO... I still miss being able to roll up windows!
So everyone seems to hate Apple computers, often quite passionately so. So you have to be the mirror image of that to try and get any kind of point across - thus you sound rather... zealous, sometimes.
I have to say though, I've become a lot less so since I got this aluminium pile of s**t. My iBooks have been like my children, this is more a bastard. The irony is, all the PC users I've shown love it, and I absolutely hate it...
