I took the plunge and did the Panther upgrade on my PB 12 rev.B between breakfast and my shower this morning before going to work... )
Since I, Gigamux, started this thread I realize that I must also put it to bed. I did my upgrade to Panther from 10.2.7 and it was a BREEZE. Took about 45 minutes counting reading the read me file and taking my time to pick out all the language files that I did not want cluttering up my hard drive.
Panther seems just as fast if not a little bit faster than Jag. I still have to go to classic for a few old apps that I have been addicted to since the beginning of time. One of them Clarris Cad still works seamless under panther! All is well and if no one objects, lets put this subject to bed.
BTW, My computer is a G4 Powre Mac 1.25ghz. I also upgraded my wife's new iMac 1 ghz as well as my daughter's TiBook G4 400 mhz. Panther is a little slow on the TiBook, but still for the stability and the future, I say OS X is here, use it.
