I like it a lot. It reminds of Whistler and Windows Mobile (yes, that's a good thing). The only thing I would change would be to tighten up the outside margins by about 50%. My instant reaction to the lower visual density was negative, but after using it for a little while, I think it's dense enough to be usable but sparse enough to be calming. It's amazing what the removable of a few borders and shaded areas does to the feeling of apprehension about email.
