I’m buying ASAP, too, but I don’t really see much in Leopard that will make me more efficient, or more productive as a Mac user. What a “productivity enhancement” means is something that saves time, reduces aggravation, reduces steps to get something done, and so on. Since most of what we do as Mac users are in various Mac applications or utilities, and not in OS X itself, there’s probably not much to be gained.
I’m inclined to agree with Wil. Almost. Actual productivity enhancements don’t come easily, and even changes from Jaguar, to Panther, to Tiger were not sufficient to make me 50% more productive.
That said, I urge everyone to check out the Leopard “guided tour” video on the Apple site. Yes, it makes your mouth water, but it also shows how Leopard can be much easier to use than Tiger, especially in Finder operations, but elsewhere, too.
Between you and me, I don’t know what else Apple could do for the next iteration of OS X beyond Leopard, but we’ll find out in a couple of years. In the meantime, only a week to go and the fun begins.
