Gartner predicted today that the tablet computer market will reach 19.5 million units by the end of 2010. Furthermore, they expect that the market is set to grow worldwide to 54.8 million units in 2011, and reach 208 million units in 2014.

“The all-in-one nature of media tablets will result in the cannibalization of other consumer electronics devices such as e-readers, gaming devices and media players,” said Carolina Milanesi, research vice president at Gartner. “Mini notebooks will suffer from the strongest cannibalization threat as media tablet average selling prices (ASPs) drop below $300 over the next 2 years.”

“Communication service providers (CSPs) who have so far subsidized mini-notebooks to drive mobile broadband uptake will shift their marketing spend to media tablets. Such subsidies will help drive adoption among those consumers who see the initial hardware cost as a hurdle,” added Milanesi. “For the rest, the freedom of paying for cellular only if and when needed, and not having to add another contract to the one a user might already have on his or her phone, is a great advantage and has so far proved successful for Apple.”
