iPad Has the Tablet Market Sewn Up. But, the eBook Reader Market is Still Fluid

It isn’t any surprise to learn that Apple’s iPad owns the tablet market with 90% of all tablets sold in the 3rd quarter of 2010 according to IDC. I was, however, surprised to learn that while Amazon’s Kindle is by far the best selling ebook reader device, it is not the overwhelming force that the iPad is in the tablet category: The Kindle accounted for 41.5% of the ebook reader market. If asked, I would have guessed 75% of the market.
