Old news, perhaps, in this fast-paced environment...
24" iMac, ordered Nov. 11th from the Apple online store, delivered Nov. 19th, did not come pre-installed with Leopard. After reading people's posts here, I figured by then that I'd be safe. Not so. At least I had some time during the holiday weekend to go through the process of doing the installation... and everything seems fine.
24" iMac
2.4 processor
upped to 500GB HD
RE the screen: it seems mostly fine but has a very slight color shift towards yellow as you go from left to right. I only notice it when I have the background as sold gray. Not worth returning, but it does take down my opinion of Apple hardware by one notch.
