'If Windows 8 and the Surface tablet flop, you'll see a shareholder revolt that will send Steve Ballmer packing by this time next year,' writes InfoWorld's Bill Snyder. 'First it was the netbook, then it was the Ultrabook. Microsoft, Intel, and the PC makers keep looking for a way to convince buyers they don't need an iPad or Android tablet. Neither initiative gained much traction, so Microsoft bet big on Windows 8 and the Surface. ... Maybe we're wrong, and buyers will decide that the new OS and the Microsoft's first serious venture into hardware are what they want. It would be a huge boost for the industry if it happens, but I'm not optimistic. ... There's been a string of bad quarters, and the stock has been frozen for nine years. At some point I think we're getting really close investors are going to demand a shakeup. When they do, it's going to be good-bye, Ballmer.
