An unofficial tracker from Shawn Dubrovac has revealed the sheer extent to which companies leapt on the tablet market following the early success of the iPad. The list shows at least 100 tablets and crossover e-readers having shipped, including not just major entries such as the BlackBerry PlayBook and Motorola Xoom but also relative newcomers such as Enspert's Identity Tab line and Notion Ink Adam. The list factors in 24 generic tablets at Freescale's booth.
