Joe Wilcox writes: "About five years ago, when blogging as an analyst, I asserted that computing and informational relevance had started shifting from the Windows desktop to cloud services delivered anytime, anywhere and on anything. The day of Windows' reckoning is come: 2010 will mark dramatic shifts away from Microsoft's monopoly to something else. Change is inevitable, and like IBM in the 1980s, Microsoft can't hold back its destiny during this decade. The Windows era is over.
What's surprising: New competition encroaching on Microsoft's Windows territory. Mobile device-to-cloud competition's shifting relevance bears striking similarities to the move from mainframes to PCs, and it is a long, ongoing trend. Microsoft's newer problem is sudden and unexpected: Competing operating systems moving up from smartphones to PCs or PC-like devices. Apple's iPhone OS on iPad is one example.
