RIM released a video demonstrating how the Playbook syncs effortlessly with a BlackBerry. For example when you read an email on the PlayBook, the BlackBerry will show the email unread immediately. This allows an easy adaptation by IT folks since no additional configuration or additional data lines are required. See video after the break:
This would not matter to the non-corporate BlackBerry owners but it does matter to those that are issued BlackBerry devices by their employer. As some of you may know, working effectively from a BlackBerry is not easy. Having a PlayBook, on the other hand, allows one to work more effectively when not in the office.
