Tablet adoption is growing faster than expected. The International Data Corporation amended its earlier projections for fourth-quarter tablet sales in its  Worldwide Tablet Forecast, bringing sales up to 117.1 million units from 107.4 million, and beefing up 2013 projections to 165.9 million. 

Also notable is the fact that IDC projects Windows-based tablets to start making a mark — albeit still a small one — in the overall tablet market. Led by the forthcoming Surface tablet, Microsoft is expected to claim 4 percent of the tablet market next year, up from earlier projections of 1 percent.

The rapid proliferation of tablet computers stands in contrast to some other numbers we’ve seen, particularly a survey from Virgin Media Business in which 500 CIOs cited the tablet as the least-valuable device in their offices. Does this mean tablet adoption is happening all on the consumer side? If tablets follow the recent consumerization of IT trend, those CIOs should take note.
