I'm not sure if PB was a 100% finished of QNX operating system. I dont' think it was. Having said that, I do own one, and found it great for the fire sale price I got it for. The browser was great, and multitasking was great too. Hardware was 1st in class. Better resolution then the Ipad and better HD camera. It was a botched and rushed release.
If the botched launch has been fully corrected with all the outstanding features that you speak of, why does nobody want them? And why do you believe that people will pay 4 times as much for a phone version of the playbook than you were willing to pay for the tablet version?
