With Apple’s introduction of FaceTime video chatting on its iPhone 4, video chatting seems to be in vogue again. You might have noticed that RIM’s freshly-announced PlayBook tablet features front and back cameras, which had led to speculation that RIM might want to lean on its massively popular BlackBerry Messenger service that has over 35 million active users to introduce video calling. If video chatting were to be integrated into BlackBerry Messenger, it would be a great way for RIM to try and put one over Apple in the video calling scene as RIM already has a large dedicated user base. Will video chatting be an important feature to the PlayBook? Only time will tell.
