That's true! Also, it's done in a way that is quick (no pause, stutter, or redraw) and doesn't completely occlude the information below it. Simple, but highly useful feedback! What I find most interesting about the interface in the demo is the fact that although the resolution was constricted (perhaps to something similar to the N800) there was much more 'usable' space due to the simple zooming of the interface. Some of the elements (the pictures) could even be interacted with when zoomed out! In the end, you have a user interface that has comparable (if not more) 'real-estate' than a desktop whilst being easily accessible. This type of an interface opens the gates for windows of different dimension, floating widgets (zoomed out view), floating controls (zoomed out view), and multiple 'levels' of these 2D window arrangements. Users could customize the zoomed-out background graphics with picture(s), widgets, and controls. Also, not all apps need lay flat. Some of them could be perpendicular to the plane (like pages of a book standing up) to allow a fan-like selection of many elements. Of course, some simple 3D objects on the plane would be fun; like big red 'arcade' style buttons, or draggable dice, or swimming fish (with a refracted water overlay animation) . What you end up with is a highly-stylish, highly-customizable, but also highly functional "zoom-top" (coined... lame? har har). Wow! I would love for the N900 to have an interface like this. A little bit of polish and not only would it look great, but would also serve a great functional benefit.
