For the first time in fifteen or more years, Redmond faces a genuine challenge to its Windows desktop monopoly. The threat isn't coming from Linux or from Mac OS X or from any other operating system. It's coming from a whole new computing concept: the "post-PC." The worry is that upstart tablets threaten to drive the computer out of the home, taking the Windows operating system with it.
