The QNX OS will allow BlackBerry users to download and use apps designed for other platforms-especially Android. The OS also handles multimedia and multitasking well. As far as the just launched BlackBerry 7 OS is concerned, this is not Harry Potter and Voldemort as both can live together at the same time. RIM says to expect a time period of 6-8 months where both can co-exist.
During the earnings conference call, RIM co-CEO Jim Balsille said that a "major feature update" is coming to the BlackBerry PlayBook with the PlayBook software version 2.0. Also expected to be shown off at DevCon, the update will add native e-mail, contracts and calendar functions to the tablet and add the Android App Player. Additionally, the BlackBerry Video Store will be supported by the tablet, which will allow you to pick from 10,000 movies and television shows to watch on your BlackBerry PlayBook.
