I had tried it out too. It was really fast, a lot more than the Linuxes I was using then - Red Hat and Mandrake. (Not comparable, I know.) I think they had a UI / desktop environment called Photon.

That 'really fast' bit that you perceived was your processor slicing 200K+ times / second versus maybe 2000 times/second under Linux or Windows. QNX is crazy fast in that respect simply because it has almost no context to switch. The soft-realtime aspect of the kernel also helps tremendously in keeping things moving, everything that is interactive runs at a high priority so you'll never see frozen mousepointers or stuff like that.

  Interesting and makes sense, thanks.
