RIM is hosting a series of webcasts that will help developers create Adobe AIR apps for the PlayBook. The webcasts will span 5 weeks and will be hosted by RIM starting on November 4th. It should be interesting to see what services will port their Adobe AIR apps over to the PlayBook and how easy they find the process. It would be cool to see something like TweetDeck running on the PlayBook.
