I do have Jaguar installed on my 500 mhz G3 imac DVSE (1 GB RAM). It works fine - much more responsive than 10.1.5 - but only after doing some necessary tweaking.
After installing Jaguar, especially if you are updating and not doing a clean install, reinsert Jaguar disc one and go to Disk Utility and Disk First Aid. Choose OS X and click Verify Disk Permissions, then Repair Disk Permissions. It may take anywhere from 15-30 minutes to both verify and repair.
When you reboot into OS X, you'll first notice that boot time is faster than before. You'll also notice how much snappier response is while using Jaguar. If you've had any instability issues, they should now be eliminated.
I found this tip on another Mac forum and it really does work! I advise everyone who has installed Jaguar to repair disk permissions now!
Another thing that helped, I think, is that I then booted up from my old Norton Utilities disc (for OS 9, not X), and optimized the OS X partition. If you upgrade from 10.1 to 10.2, the result is severe fragmentation. Optimizing can only help, I'm sure.
(I should mention that I have the $19.95 upgrade discs, which stupidly will not allow you to do a clean Jaguar install!)
After doing all of this, I'd say that Jaguar is almost as responsive as OS 9.2 in a G3 imac. At least it is now close enough to the point where I no longer feel that the OS is lagging.
Although I only had to pay $20 for the OS X upgrade (I had bought a PowerMac in July and, no, I feel no guilt about inserting the upgrade discs into my old Macs as well), I do think that I would have been livid if I had paid full price for this OS update. Yes, it is a little bit faster - but not a blazing difference. It's merely a performance tweak that was expected (and should've been there in the first place). Other than that, what does Jaguar offer? ichat? I couldn't care less about it. It was thrown in the trash as soon as I booted (along with all other apps I won't need). The new audio core is promising, but OS X still has some serious audio issues that Jaguar did not fix.
And why can't Jaguar deal with mounted disc images? This is really annoying to me, because it is something I use a lot. All earlier versions of OS X had no problems with this, so why is there suddenly a bug now? Grrrrrr.
But the real POS is Quick Time 6 (which Jaguar installs by default, overwriting your existing QT 5 app). It's just horrible - absolutely useless. In the past, I had early beta versions of QT 4 and 5 that were more functional than QT 6 final! Video playback is choppy; full screen playback is out of proportion and pauses constantly (doesn't matter if you are using the latest dual proc Powermac or an old G3 imac). I had to find a QT 5 reinstaller for all of my machines.
I just can't believe that Apple released such a bug-ridden QT version. This is easily the single worst QT release ever; this never should've made it out of the door.
As I said, I only had to pay $20 for Jaguar, so I'm not really going to complain about the price, but I can't begin to understand how anyone who paid full price isn't screaming for blood.
So is it worth it? Only if you are paying no more than $20 or can "borrow" the discs. I'd also suggest that you have a QT 5 reinstaller on hand before you upgrade to 10.2.
I don't care what anyone says. Jaguar is NOT a "major upgrade". It's a performance tweak that works, yes, but that's all it is. (Unless you think ichat and the like is worth every penny.) It's full-price-no-exceptions cost is simply not justifiable.
