Apple's Leopard and old Macs (Score 1)

Let's wait for release of Leopard before judging it. There are many talks about "useless" underhood changes, but that is what driving all third-party applications and that's what we use everyday. If you don't like that, you can always turn back to stuff like old good terminal applications and write emails, browse web through text based, "uncluttered interface" :-)
And, after all, topic is 800MHz G4's and Leopard ;-) I hope my PB G4 will run it or I will need to upgrade to Intel-based portable Mac.
