RIM's Woes

I own a BlackBerry, personally I like BlackBerry's, I think they are alot better than Iphone.
However, I think that RIM fail to understand the leverage that WhatsApp has vs BBM.
BBM was the original, and us in the MTV generation love the idea of messaging globally, it reminds us of MSN Messenger and Yahoo. Perhaps RIM needs to work out how to intergrate BBM with their BlackBerry Desktop Software and allow for people to message from BB-DS to BBM's on their list. They need to "better" the Apps offered on Iphone
