RIM looks like a great investment. As mentioned in this thread, they have very long term contracts so they won't die anytime soon, and they Are trading at such a ridiculously low premium that if they don't die they're bound to go up by a factor of 5. Heck their market cap is 1% of apple's, so (very roughly speaking) if they hold on to 5% of the market you'll see a massive gain.
I used to think that apple had built a fortress around the iPhone with its app ecosystem. After getting a new iPhone I realized I didn't need to reinstall most of my apps, and I stead its mostly: web, messaging, phone, music. I left blackberry way back when because of its horrid web browser, but if they fixed it then it'll probably my be more than good enough for business (many of which have the phones locked down to begin with)
