Troy isn't seeing any upgrade issues with the Mac, and other people I know haven't seen any either:

OK, so where are all these problems and signs of almost Microsoft Vista class suckage that some people have reported with Leopard? On my iBook G4 it feels a bit more spritely than Tiger did. The only "problems" I've experienced relate to recovering some application data since I opted to do a clean install and completely reformat my HD. If I hadn't renamed my main user account to create a separate admin account, I bet the migration assistant would have recovered most of it.

I'm starting to think that the issue here is simple: the sea of Mac users has gotten bigger, and interest in it has grown by leaps and bounds. So, any issues - no matter how rare - get a lot of play.
