I'd be curious to hear from anyone that has a Blackphone. How does it compare to other phones you have used? Do you plan to get a Blackphone 2?
The blackphone is pretty poor. Maybe most androids are this poor, but I feel ripped off. I re-enabled the iPod for using silentcircle at home -- the call quality is better !!
As far as security. I don't know. Shark repellent works fine all the way up until you die by shark.
