What's so unintuitive about it? I looked at the picture for 3 seconds, and could tell exactly what does what. That's the very definition of intuitiveness.
It could be better, I guess. As far as aesthetics are concerned, the icons have a little too much shine to them, and it isn't the usual bright but soft look Apple seems to go for. But hell, it could be considerably worse.
Geez- some of the icons have Reflections and some don't. This really is the ugliest thing they've released in a decade. If they wanted it to be like iOS, then the categories should have been folders, or you should be able to create your own folders. It's a mess.
