In this past year, tablets have dominated sales over e-readers. Estimates are made that Amazon Kindle Fire has sold over 2 million units, and Barnes & Noble has sold a million of its NOOK Tablet. Both vendors were also successful in selling their previous models at the discounted prices. However, you shouldn’t forget another very popular tablet — the HP Touchpad, fire sales of which were bringing over 700,000 tablets in the hands of eager customers. Then, as the numbers of RIM Blackberry Playbooks sold at similar numbers to HP’s Touchpad, the popularity of having a well rounded more powerful device has grown significantly.
