Hey, Teflon Ballmer. Look, isn't it time? You know, time to quit?

Those who upgraded to Windows 8 aren't the only ones unhappy with the new touch-driven operating system - Wall Street is too. Just don't expect any of the criticism hurled at Steve "Teflon" Ballmer, Microsoft's shy and retiring boss, to stick.

But all roads leads to Windows, and version 8 of the operating system is actually Microsoft's second major disaster in something it's supposed to be able to do with its eyes shut: its second "New Coke moment", if you will. The first was Windows Vista, Microsoft's last big bet to reinvent the software industry with a brand new user interface, web communications layer and storage subsystem.
