Personally I think it was a mistake to bet the house on an operating system like Window when it never proved itself in the market places. Simply put It is not popular either with consumers or Enterprise.
How would you measure that? By comparing NOK vs. BBRY sales? If so good luck. I heard BBRY won't let you confirm it won. You see, you need sale figures to declare a winner. If sales are so low that they are too embarrassed to release them, well that's....embarrassing. Keep holding BBRY. Maybe Q3 will feature numbers.
The only war that BBRY will win is to be bought out or go bankrupt, the direction they racing towards futher supports their CEO's comments that putting that company up for sale was on the table. Blackberry gave it their last best shot, an all in one, and they have failed, their phones arent selling and their playbook tablet isnt selling. Good luck with that BBRY stock, you should sell all of your Apple and all of your Nokia, you should go all it on BBRY since you have such a conviction that BBRY will survive and thrive.
