One can't really tell from a promotional video, but the main thing that stands out to me is the improved home screen over iPad. It's too "technical" to be mass market in this version; viz. "Books \n 3x3" type stuff - my parents won't know what 3x3 means, even after explanation. Even I'm only guessing is the size the widget takes on the home screen. However, assuming they fix that, it's rather an improvement on Apple's iOS SpringBoard, which is looking rather dated (alongside their notification system). Here's to competition accelerating an upgrade in iOS 5!

The rest of the applications, one can't really tell in short clip. A lot of them - mail, video chat etc - seem very similar to what one would find elsewhere, except with the Honeycomb chrome (take it or leave it, as personal preference dictates). In others, I worry they've gone for eye candy over usability. For example, in "Books", the circular scroll is all very well, but I can't see any way of telling how far through your collection you are, nor where the book you want might be. Of course, the is prerelease promo, so it might be obvious in the real thing. What most people don't seem to get is that Apple tend to use eye candy only when it's useful - not just to look like something in Minority Report. Even they don't get it right all the time (I'm looking at you, Time Machine animation!). Eye candy is really cool for promotional videos, but when you're trying to use the application for the 4562nd time you really hope that it's added just to enhance usability, rather than impress CES visitors.
