Apple has already managed to sell over 15 million tablet computers in the last one year and there are predictions that this new tablet will help Apple to fortify its position further in the tablet market. But this may not be as easy a task now with the competition too stepping up the heat. Motorola Xoom, which was crowned the most promising gadget at the CES and touted as the strongest competitor to Apple iPad will start retailing from today. Just like the Apple iPad, Motorola Xoom is also a 10.1 inch tablet device but it runs on Android Honeycomb. Additionally there are more tablet devices from Samsung (more Galaxy Tabs), LG (Optimus Pad) and RIM (with its talked about PlayBook) that will seek to challenge Apple in this segment. All in all 2011 truly looks like to be the year of tablets with many more innovations being added in this sphere.
