He sounds like the Linux fans that used to say (and probably still say) "oh, man, Ubuntu is so strong right now, they're right on the brink of fighting Windows. No, they- you give it six months and we'll see big Ubuntu laptops. I swear, man people are gonna get sick of Vista. Window 8.1 is crap and an Ubuntu Revolution is coming. It's just inherently more stable. It's unix, man. Just... in five years you'll forget Windows. People are gonna get sick of their computers slowing down on 'em."

This arguement is sort of correct. Linux, like Blackberry, is niche. up until recently, in certain segments you would only see linux. web servers come to mind. It's still a big player in that market. Other people try to put things like Ubuntu in front of people that don't want Ubuntu, then you get people saying Linux is joke and is dead or dying.

BlackBerry is having the same problem. It's a device for a very targeted audience. I'm glad that blackberry has figured out who it's target audience is finally.

To hit your other points, Android may be open source, but there is more to security than code. BlackBerry has more time in navigating government and military certification procedures than any other mobile phone/mdm vendor (as well as being the only mdm+phone vendor out there unless you consider what microsoft puts out an MDM solution). they also have a business that makes money by being secure, as opposed to a company that makes money by selling ads through data-mined user profiling. if you don't believe this, just look at Samsung. They throw money at problems to make them go away. they started up their "Knox" system, which was going to be a secured device environment. They decided to let BlackBerry handle it. What does it tell you when the largest android company in the world hands their security platform to BlackBerry?
