- QNX is better for real-time things

- QNX can be a lot leaner than Linux

I liked QnX. It used a micro kernel architecture. I used it on 286, and later 386, based computers when I was working for a market research company back in the DOS era pre-Windows. I used versions 2 and 3 of it. GUI stuff wasn't added to QnX until version 4. I never used QnX version 4. The 386 and 486 computers were fast enough that I was able to port the entire system to DOS only. I don't often hear about QnX. Interesting to hear of it used in a commercial product.
