Not to harp on this, but that right there is one of the things I miss from the N800. In Diablo you can see all running programs without pressing a button if you're not running full screen, and if you're running full screen you have a button on the face of the screen that will pull up your list of running applications over the top of whatever program you're currently running.

With the N900 I have to pull out the keyboard, press two buttons on opposite sides of the keyboard, and then many times either nothing happens at all, or there is a big delay before the grid of running apps is displayed.
