Recent update about BlackBerry PlayBook, due to battery issue, might push the release date further to May 2011. According to analyst Shaw Wu with Kaufman Bros., the battery is only capable for few hours of power, which might not be a good competitive edge in the market where Galaxy Tab got 6 hours and iPad up to 10 hours of battery life.

blackberry-playbook-tablet Wu also further explains that QNX is not designed for mobile environments, but more toward devices like network equipment and automobiles where battery life is not the biggest concern.

Furthermore, the lack of online applications supports for BlackBerry PlayBook might also prevent users for getting the tablet, since other existing tablet manufacturer such as Apple, provides huge online applications store for its users.
