Today I finally took the plunge and installed Leopard on my MacBook Pro. So far nothing seems obviously broken and so I’m pretty happy. At the same time I haven’t really noticed much difference at the moment either. Preview might be sharper and shinier. Desktop icons now have little previews. The machine is maybe a bit faster and runs cooler when doing the same tasks, particularly compiling which is probably faster than I have ever seen on a desktop machine.
Mostly though I am glad that everything has been migrated with zero pain.
