The one hardware button he thinks is worth having is the one that seems to me least useful (well, except search). "Home" would be a perfectly good option to have in the menu, or a function of holding down the "Back" button. "Back", on the other hand, is something I could hardly live without, and "Menu" is at least understandable.
