BlackBerry Playbook OS

[Rihanna]

The BlackBerry Playbook OS was developed by Research in Motion (RIM) for its Playbook tablet. It was based on the QNX Neutrino real-time operating system designed to run Adobe AIR and BlackBerry WebWorks applications.
The OS has been received really well by reviewers worldwide despite the lacking features in the original release. Later on, most of these have been added and the OS even got a native Android app launcher (though app support is rather limited).
The Playbook OS is no considered an evolutionary dead-end as no new generation of tablets have been released by RIM.
However, RIM’s latest endeavor – the BlackBerry 10 OS – is similarly based on QNX and it will replace the long-standing BlackBerry OS on smartphones in 2013.
