Buying RIM would take brass balls right now.
Stating the obvious here, but it could go either way.
What Rim needs is a home run with the BB10 (but that won't be enough) AND RIM NEEDS a major security breach into either an Android system, or the Iphone system. Preferably by the Chinese, and preferably into the US gov't networks.
The one thing RIM has going for it is security, but people overlook this in their rush to have a phone that barks like a dog, or speaks Newfie.
All it will take is ONE major security hack job in the US gov't network and RIM will go orbital. It's not a question of if it will happen, it's when it will happen and will it be soon enough to save RIM.
