I even own a copy of Lion (because I bought my computer close enough to its release that it was free for me), but haven't installed it because not all of my (big, commercial) apps are compatible with it yet. Like, announcing the next OS before developers have gotten their apps to work with the current one does seem a bit much.

Also, neither Lion ("Now with a working maximize button!") nor Mountain Lion ("Play games with friends on iPhones!") seems to have any really compelling features.
