Being a G5 owner, I qualified for Apple's Up-To-Date program, and so I forked out my $35 and they sent me Panther. So then, having bought a Firewire backup disc, and backed everything up, I unplugged the drive (hey... I've been paying attention...), started up from the Panther install CD, and thought, well, maybe I should reformat my drive (to keep everything clean... in the past I've had weird things crop up when I've installed over an older version). So I reformat my drive, go to install Panther, and - hey presto - i'm not allowed to, because I don't have an older version of OS X on my computer. There is absolutely NO REASON why just because I'm an Up-To-Date customer, I shouldn't be allowed to wipe my drive and start again. In fact, if something crap had happened - like my hard drive had broken or something - then I would have EVERY RIGHT to install Panther from scratch. I was eligible for Panther because it's the FIRST STABLE (I know this is arguable!) OS release since I forked out 10 grand (that's right folks, 10 grand) on my new system, and the first release to take advantage of many of my big, fast computer's features. So. I'm ringing Apple right now and telling them to take a good, hard look at themselves. EDIT: I rang them. They told me to get lost.
