Doesn't run Mac OS, so it's not going to be much fun if you're upgrading from a previous Mac. It's also probably going to be a bit more of a pain to keep it working (there were lots of things I didn't like about Mac OS X but one thing it was pretty good at was being plug'n'play and generally not fucking up - the latter being something Windows is not so good at).
Agreed on both counts, the reason that iSheep like me don't look at competitors I'd say is ultimately what you pointed out (at least for me that's more than half the reason - no maintenance!); and I agree on not being offended by the word iSheep which I had never heard of before and I think it's funny.
I bet you (skrowl) were downvoted just for using that word. It's short and sweet and conveys the necessary disdain you wanted to convey. I don't see what's wrong with it.
When I had a Windows machine I had to keep up with spyware and know all sorts of arcane things about the OS just to keep it chugging. I had HijackThis on a thumbdrive at all times. Nowadays I use my Mac as if I were punishing a computer, and it keeps on working without a hitch, no drivers gone wrong, no registry crap to worry about. That's why I'm an iSheep.
baaaaaaa
