Yes, I am actually! I had an iBook 600 that I gave to my sister because she needed one for college (I could use the iMac more because I could upgrade the RAM and HD farther). For the stuff I do with a Mac, the iMac is just fine. I'd like to get a mini, though to replace it. If I do, I'm gonna wait a few months until the 1.5GHz models are completely in the stream.
Update: I tried the installer again after a reboot. If you simply wait about TEN FARKING MINUTES, it'll finally finish "searching" and do a half-second install and be done.
