Nobody seems to be asking this about Leopard...

[whooleytoo]

My question is not if it will run, but if it will run well.. I have a G4 Mini with Panther on it, and I'm just not sure if the jump to Lepord will be more hassile than it's worth (ie RAM upgrades, possible system slowdowns, etc)

I have a G3/350 running Tiger which is fine for most everyday tasks (though of course it won't run Core Image, Core Video, or work well with the latest video codecs). The way I see it, there isn't much running difference between Panther and Tiger on an old machine, the main performance difference seen when upgrading may well just be due to doing a clean install of any OSX.

I'd expect Leopard to be similar in performance to the others, bar increased memory usage.
