According to Kaufman Bros. analyst Shaw Wu, the BlackBerry PlayBook is delayed until May 2011 due to battery life issues. Wu's sources have said that the current battery on the PlayBook only lasts a few hours. Compared to the Samsung Galaxy at six hours and the iPad at ten hours, the PlayBook will be a tough sell. With a dual core processor and 1 Gb of ram, the PlayBook seems to require a larger battery to power it. Also, the QNX OS that the PlayBook runs on was initially designed for network equipment and automobiles, devices where battery life is not a huge consideration. Hopefully RIM can pull this off with minor adjustments to the design.
Update: Late last night, RIM released a statement denying these claims. Read the full story in the BlackBerryOS forums.
