QNX is a real-time operating system. It was originally based on Unix, but, unlike Linux, it made no attempt to remain compatible. The main advantages of QNX over Linux is that the o/s kernel is configurable to a much greater extent; they call it a "micro-kernel", and it can fit into a few kilobytes of memory. QNX has become very popular as an embedded operating system for use in television sets and cash registers. Although QNX is Unix-ish enough for code to be ported without too much effort, programs that are designed as Unix applications miss out on the full power of the operating system. QNX is a message-driven operating system -- right down to the kernel -- and using messages to synchronize tasks means much better performance than relying on semaphores, etc. In a word... QNX is a superior alternative to Linux, but it isn't 100% Unix-compatible, and as far as I knew it wasn't free up to a few months ago.
