Seeing the success that RIM has had with this strategy, Google and Apple have rushed to bring similar products to market.
So what's the answer? Currently, I use Google Talk/Chat, Google+ Messenger, Facebook Messenger, Whatsapp, and when iOS5 comes out I'll also use iMessenger. With my Blackberry carrying friends I feel a bit left out, and have to hope they use Whatsapp. Of course, in an emergency, good old SMS is still available, but I would love to be able to move away from SMS entirely. Until one of these companies can build all this functionality into one app, I'm forced to keep using a combination, depending on whom I'm chatting with. What a mess!
And who owns the rights to the Messenger name anyway?
Thanks for reading.
