A QNX-powered operating system that powered the Blackberry Playbook, a Flash-centric tablet that suffered serious design flaws (no native e-mail app?).
It was effectively discontinued just over a year after launch due to a shift in focus towards the similarly QNX-powered Blackberry 10 phones, and was officially cast into end-of-life status and the end of "reliable service" on January 4, 2022.
