There was a time when companies needed PCs for everything. Those employees that stayed in the office used desktops, and for folks that would travel around town, getting their hands on a notebook was always a good idea. But in the last couple of years, tablets have become popular. And now, devices like Apple's iPad, the Research In Motion BlackBerry PlayBook, and so many others, are starting to cannibalize PC sales. In the consumer market, that's especially the case. And according to a recent study from research firm IDC, such cannibalization is also starting to affect the corporate world. As a CIO, you probably already know that. You understand that your employees need to have the right tools for the job and increasingly, the right tools happen to come from companies like Apple and Samsung. It's an odd shift, for sure. But it's something that no company would want to ignore in the coming quarters and years. In the following slides, we're going to examine IDC's findings, which seem to predict the PC's fall from grace, and discuss the market as a whole. The IDC findings might just surprise you - and make you wonder if PCs are in as much trouble as some tablet makers might want you to believe.
