I am looking forward to receiving this week. I only wish that I hadn't jumped the gun and got one with Tiger instead of Leopard.
I know that Tiger will run much faster and smoother on this machine, but still like Leopard, as I had it before on a 1Ghz G4 Powermac and it was great.
I did find a 1GB PC3200 stick that I can install in the "non-user" slot...most likely replacing the factory 256 thats in there. Would be nice if the installed 256 is actually in the so-dimm user slot.
This way I would have 1.25GB of Ram, but no biggie. I plan on getting a 1GB so-dimm off of eBay and possibly an Airport Extreme card to complete the iMac...should be fun!
Probably just use it for iTunes, syncing apps on my new iPod touch (which is extremely cool and recommended), photo viewer, etc, etc.
