Go ahead and do your DD. QNX has a lot going for it, and so does the playbook. It's not selling well cuz it was released prematurety and they did a #$%$ job promoting it. It's been a couple years now, and it's been perfected. The playbook still needs to be upgraded to BB10, I like it the way it is. Solid peice of hardware.
and seeing that the price is still low on it. I'll probably buy another one for the house/kids. Can't beat the price.
