As my signature states, I have a 700MHz iMac G4, 15 inch. It's currently running Tiger and I'm pretty happy with it. TFF works pretty well with tweaks, and there is some software that supports it. Normally I always prefer Tiger. But in the past month or so I've seen more of the advantages to Leopard. Like Leopard-WebKit. Or the Sierra theme (soon). Or access to the full selection of software on the PPC Archive. To be honest I want Leopard on this Mac but I don't want it to be slow. So now I'm looking for some advice by anyone who has hacked Leopard to run on a Mac below the requirements. Is it too slow to be useable? Are there any hardware problems? Thanks so much for any advice you can provide. P.S. Please don't go telling me how to get Leopard on this Mac, I already know how to do that.
