i forgot that it was being released today and I happened to go by the Apple store this afternoon and looked at it on the new iMac. The new Finder with the preview is great. Spaces is pretty useless for me. Time Machine is just a backup tool right? The rest seemed to be just just cosmetics.
I think I will wait for for everything to update and then buy myself a copy.
I'll get a copy as soon as I find out if the installer does a hardware check first. Recommended hardware is an 867mhz G4 and above. I'm have an 800mhz G4. I've been hearing reports that you can't proceed if you don't meet the Apple recommended specs.
