Show of hands. How many of you guys will just be testing Leopard-loaded demo macs weeks or even months before actually purchasing it? Time machine is mainly the thing I'm interested in, and I'm willing to pay the $129 for this and a finished bootcamp alone. But just the same I'd prefer not to suffer the plight of the first wave. I see no reason to jump on new OS's the moment they come out, but I hope enough early adopters snag it quickly and start posting their cheers and gripes to give me a general idea of some of the more important flaws and improvements. I've only had Tiger for a year, I can definitely bear to stay with it a bit longer.
