The tablet market in 2011 will be comprised of a wide variety of devices from large manufacturers (like HP and Dell) as well small manufacturers (like Viliv and Notion Ink). The total volume produced is expected to reach a staggering 57.6 million units, up from 17.1 million in 2010. The bulk of these devices will be powered by some flavor of Android including the tablet-optimized Android 3.0 Honeycomb. RIM is also expected to jump on the tablet bandwagon with its QNX-powered BlackBerry PlayBook, and HP reportedly has a webOS tablet in the works. In the face of this growing competition, Apple should remain confident as the iPad is projected to retain its title as market leader for at least the next two years.
