Congrats, the iMac is a fine machine. Nice to (finally) see 512MB of RAM as standard and GPU bumped to 128MB.
I'd be tempted myself, but I'm too used to dual-procs.

Once my bills are paid a dual 2.7 will be winging it's way to me.
BTW, what is up with the low-end PowerMac? The iMac has twice the hard-drive space, twice the RAM, twice the video memory and a 17" LCD, for the
same price. It wasn't so bad before the iMac was refreshed, but now it looks terrible.
