One would think that the live tiles with continuously updated information show more "connection" with the user.
I have long had the theory that the people at the top who could have done something against that (notably Steve Jobs) simply don’t care about that discrepancy, that’s why it can continue.
It's just a browsable report of the status of things you care about, with the UI more trying to get out of the way, and provide options, than be a "thing" in your world by itself.
On that note, It probably should (and perhaps will) become more subtle over time. I'd prefer it taking the same approach as classic mac os: stay in black & white so that the user's real data is in color. They won't do that, of course, but a subdued palette could really help. Of course, then the individual widgets need to really bring home their content's presentation.

Can you really say that the app above has no personality?
