@dahat: It wasn't "most users not clicking the start button", just that the number of users clicking it was trending downward. That's not the same thing at all.
The point isn't that the start menu is "bad" and had to be removed because its use is trending downward, or because of the new taskbar. The point is, given that the taskbar takes over many of its functions, how can the start menu be evolved to find a new role and also fit newer trends in use of PCs? The start screen in Windows 8 is an answer to this, it's not the only or necessarily ideal answer, but any problems or deficiencies need to be addressed by actually solving the problems not creating a parallel start menu leading to two places to look for everything and implement everything which just makes no sense.
