I still think that the stock should be valued much higher given its popularity worldwide, in places such as Britain, UK, South Africa, Australia, the entire Mideast, etc. Just because Americans have switched off of Blackberry does not mean that the company cannot be successful.
That said, what other phone is there for someone who is business-focused? Don't you need a physical keyboard to send long, accurate e-mail correspondences? Also, Blackberrys are easily the most secure thing out there.
Blackberry definitely has a future and its stock price will likely rise to the mid-$20 mark by next year.
