This seems pretty Start Menu-esque, but I'm interested to see if the need to rollover will impact my workflow when moving between Mail/Reader/Calendar.
That's interesting because it sounds like not everybody has the same stuff in the bar, but yet, the order doesn't match what people are actually using the most, which they know. (in my case, I use Reader a lot, but it's under "more")
I think I like the look though.
