I've been forced to use Macs at work for the last 11 years. I would never allow one in my house.
I exactly the opposite. Been a Mac user at home since the Mac Plus--Amiga user before that. I LOVE the Mac! PCs I tolerate at work because I have to, but I have a dual processor G5 (with Parallels and RDC) that's my main work machine so I can pretty much stay in a Mac environment 75% of the time.

Sticking to the original post, at home I currently use a 2.4 GHz Intel Core 2 Duo iMac. Great machine! It's serving me well.
