Over the past few years, the growth of mobile platforms has emerged as the most innovative and exciting technology trend in some time. Before the launch of the iPhone, Microsoft was suffering through the tepid launch of Windows Vista, and Apple had released its fifth iteration of Mac OS X since 2001. To put it simply: Desktop operating systems had gotten boring. There was little in the way of innovation on top of them. And attempts at extending these desktop systems to new devices, like Windows-based tablet computers or the Apple TV, never found widespread success.
