Wouldn't it be a great feature to have OTA back-up for the Playbook! I sure wish I could back-up the Playbook to my computer via WiFi or Bluetooth. Why isn't there a Playbook "Library" that gives me an option to back-up the device to a 'cloud' server?
I am certain RIM could create a back-up scheme that would not require all of the software to be backed up. RIM just needs to identify the application(s) list and the associated data. RIM keeps the application in just one location in the 'cloud' with no need to duplicate it, and just back up the data for each user.
