Wow. A little late to the party here, I know, and I don't want to be too critical as I know you will have put a lot of work into this, but I have to say that interface looks pretty horrible. I'm not a UI designer by any stretch of the imagination, but first impressions would be:
Like others earlier in the thread I don't really understand why it is so different to the Mac and iPhone UIs. Surely starting with the Mac UI and blending it with the iPhone one to take the touch UI and screen size into account would have been a reasonable approach, as would taking some cues from how the built-in iPad apps plus other Apple apps like Keynote etc. do things?
Sorry!
- Wasted space. Lots of it. (I understand that this might have changed now)
- Boxing the list items in the right pane waste space and IMHO is ugly, why not make it more like the Mac or iPhone UIs?
- The Inbox and new task icons look far too big.
- The upward-pointing disclosure arrows are a confusing departure from the way the Mac UI works. Why not have a right-pointing arrow at the right side of items that have things to disclose and no arrow if they don't, like on the iPhone?
