BlackBerry QNX is an embedded operating system targeting applications in the automotive, general embedded, and medical markets. However, it is not your garden-variety embedded OS: QNX is a full-blown, UNIX-like, POSIX-compliant operating system with all of the features you would expect of a desktop or server-class OS. Compatibility with other systems means that, at least in theory, porting various open source projects to SDP 7 should be a relatively easy task. And so, while there is no official support in this release for a desktop environment, there is nothing precluding someone from building such a system. With that in mind, I set myself the task of building a BlackBerry QNX 7 desktop.

If I remember correctly QNX used to ship with a window manager ages ago – it was called Photon. Quite fast and powerful even without any hardware acceleration. What happened to it?
