While I'm waiting, I might as well post [my performance numbers|PerformanceComparisons] for Jaguar. I'll update this post when I finally get Panther installed on my laptop.
I'm willing to bet my new 2.6 GHz Dell Dimension 8300 blows the doors off all of these numbers. We'll find out later this week!
I'm now at my local local Apple Store trying to get this damn upgrade accomplished. The guy who's working on it thinks its fingerprints on Disc 1 that's causing the problem. I'll be fricken livid if this is the problem. If it's not, that means this guy doesn't believe I know what I'm talking about and I've just wasted 30 minutes while he sees the same behavior that I've seen. If it is fingerprints, I'm an idiot and I'll walk out of her with an upgraded machine in 30 minutes or so.
Update: A nice stack trace towards the end of disc 1 finally prompted them to try new CDs. Once again, more waiting...
Update 2: New CDs didn't help - the upgrade still froze when installing Asian Languages (or something like that). I left it there for them to fix. Hopefully, I'll get back an upgraded machine in the next day or two.
Update 3: I just talked with the guys from the Apple store - my 3rd party RAM was causing the problem. They removed it and Panther installed just fine. Now I get the joy of installing it again (when I get home tonight) and hoping it works. If not, I'd better get my money back from OWC!
