I would call that folder part of the resources called upon in the assembly of the All Programs Panel largely because it is just part. Unless you have manually arranged it thus there is no folder that contains all the constituents of this panel.
The XP start menu cascaded ... if that's not folder expansion, I don't know what is!
And as for being a more productive method, the W7 start panel can be brought up and completely navigated without your hands ever leaving the keyboard (which makes your earlier comment about selling more mice even more ridiculous!) and without needing to memorise weird key combinations - all you need is the arrow keys and Enter. How is that less productive than chasing cascading menus across the screen?
