Those last few posts made me start to think Apple's being overly ambiguous about Snow Leopard (It's coming out soon, yet no real announcement? We know of about 3 features, none of which are exciting or really new to make old users upgrade?) because they are waiting to see what Microsoft does, and then try to improve on it.
I wouldn't be surprised if the dock got a new upgrade and the overall look became more like Windows 7. It seems like Apple's waiting for Microsoft to make a move.
That's not a bad thing, but it does warrant some introspection by some posters here... Microsoft's not the only one "copying."
With that said, Windows 7 is on every computer I own, including my MacBook. I hardly miss OS X. In fact, the only things I miss are Adium and iChat. Everything else I find to be the same or even better on 7.
