To be honest a few things that I love about mac I did not love to begin with. I have been using them for 11 years now, and I find that it is not always obvious where they are going with certain features.
Granted, MobileMe was a disaster and it is leading to iCloud, but when you look at Mission Control, does it not scream touch screen PC to you? I know there is the iPad etc. but this added functionality really opens them up to bring touch screen into the home, in an iMac for example. I am not saying I like it - I am still using SL partly because of it - but being able to bring iOS and OS X together really lets Apple start to debut the idea of the 1 operating system that is sure to come in the next 5-10, as more ways of interacting with computers (inc iPad/iPhone) come into play.
Who knows what the people at Apple are dreaming up!
