For the iPhone 4 you were able to preorder and specify a particular store you would like to pick it up at. On release day there were 2 lines at the store; one for those who preordered and one for those who did not.
Besides their messaging and email, what features do they bring to the table that could be considered "a lot"?
The fact that they bring little else is part of the reason they're getting hammered. It's much easier for competitors to implement these features on their own than it is for RIM to up their game to the level of the competition.
When I use multiple monitors I drag the top bar to the monitor I'll need it (using the Displays preference pane) in depending on the type of work I'll be doing. I rarely if ever "need" the top bar on both as the extra monitor usually serves as an adjunct to the one I'm doing most of my work in. Your circumstances may differ.
