I am waiting to buy an iMac until the refresh. Since I have never been through one of these, I just wonder what it will be like. I have no Apple store near me so it would most likely be the Saturday AFTER the refresh that I could get to one. What is store stock like after one of these things? Would I do better online at Apple.com? I have been through 3 iPhone launches (skipped 3Gs), and I know they can kill the Apple.com store. Are the refreshes similar? Thanks.
