I got your answer!
I just upgraded to Panther over the weekend on my G3 800 iBook.
I have been thinking about it for a while, then a friend of mine who upgraded his system to OSX Server, gave me his old copy of Panther that he does not use.
I cloned my HD to an external FW drive and did a test run there. All my apps ran great, the system seemed faster, but I thought it might be the 7200RPM external HD. The test I did was with 10.3.0.
Once I felt comfortable with it, I installed it as my main system after cloning and backing up my Jaguar system and all my files. I did a system upgrade (not erase and install, or preserve old system), let the installer optimize my system, and got 10.3.6 installed.
The conclusion? holy cow! It rox! My system is at least 10% faster, is way more responsive, all the little changes in Finder and the control panels are great, and Expose is a marvel. I would never go back!!! ok, if I feel nostalgic I might
But I think it was a great thing to do, and my system feels like a new machine because of the speed and all the nifty little extras.
Keep in mind that I got the copy for free, but I was looking around and tried to buy a used copy for $60 or so. For that, I think it is more than worth it.
If you are going to pay full price, then I say wait, just because I think buying Tiger for $129 in the next 6 months or so will definitely be a smarter move money wise, etc. If you can get a cheap copy of Panther, then do it do it do it.
Disclaimer : I am very careful with my system so I cloned it and tested Panther with all my apps and files, and I still have a clone backup of my HD with Jaguar. I suggest you do the same thing with any OS install, or at least backup all your user files.
