My experience with QNX is quite limited, but the OS is very general. There is a desktop GUI that is powerful enough to serve as part of self hosted software development environment. Generally, the tradeoffs are made to keep the core microkernel small and to give the system reliable guaranteed response times rather than raw performance because it is intended for hard real-time environments.
