I don't like the idea of having bits and pieces of Panther OS information on a Tiger running machine you see. And yes, I am a format nut as a Windows user...
Hmmm ... I'm beginning to see your concerns here. Okay, the first thing you need to understand is that an Apple OS "update" is completely different from a Windows update. You would get a Tiger upgrade CD in this scenario, but the CD you'll be getting will only be valid on machine that already have a full OS X install already on them. For example, with Panther, Apple sent update CD's to people that bought machines within a certain period of the release date for a reduced cost. These CD's were not "retail installs" in the strictest sense because they wouldn't let you install on top of Mac OS 8.x or 9.x, you had to have some version of OS X installed already for it to work. As far as I know, this is the only thing that separated them from the retail install CD's that you'd buy off the shelf in the Apple store. So, you're technically "upgrading" the OS, but doing so by putting a clean install of Tiger over everything.
The transition from 10.2 to 10.3 was pretty seamless for most people. A few kinks here and there with the initial release, as is always anticipated, but for the most part, not a lot of problems. The only real concern you should have is whether or not developers have updated their software for Tiger, but you'll find a lot of stuff still works without having to update, making OS X very friendly.
I would personally wait for the announcement so you can hear the update policy just so you don't get screwed. Tiger will install nicely over Panther, so no worries - that's just from personal experience doing the upgrade thing from Jaguar to Panther with an update CD. I sure someone else can offer you a technical explanation as to why this is possible ... hope that puts your mind slightly at ease...
