Hahaha you guys are critizing it so much it's hilarious... but what can you expect on an apple rumours site...
I have a macbook and love apple, but I can't lie, this thing looks amazing! The only thing that the ipod touch has over this is the apps and the internet browser, as I'm assuming Microsoft's won't be as good judging from what I've seen of IE mobile.
The UI looks amazing, I love the animations and images, way better than apples
I have yet to criticize it. Frankly, I find the usual 'what can use expect from a apple forum' site hilarious. Well, duh! Go to a Windows forum site, and see how much they love the Zune. It just goes with the territory.
As for what I saw of the Zune UI, the guy had to tap multiple times to bet many things to work. Other than that, it looked decent, but it is hard to tell from a small video. I'd rather see it in real life before I make any final decisions on the thing.
