I upgraded my computer to Mac OS 10.5 (Leopard) over Thanksgiving. I'm now getting used to some of the "over 300" improvements in the system.
I think the absolutely best new feature -- in fact the feature that sold me on Leopard -- is Time Machine where back-ups are built into the operating system. For years we've gone around telling people, "Always back up your computer" -- with the likelihood of anyone actually doing it around nil.
Here comes Apple and they make it part of the operating system! Really I think this is the most remarkable thing I've seen since they incorporated iLife into the OS. Amazing stuff.
