content: I recently tried to play around with QNX, because I was curious about exokernels. Come to find out that even if you want to test the OS out, you've got to pay for it - no shit, 30 day trial costs money. BlackBerry are idiots - they suck up such an interesting property and then charge devs JUST TO TRY IT OUT. No wonder it isn't going anywhere. But back on point: I didn't know that NT was based on VMS - that's actually interesting. In what ways did MS steal VMS for NT? Also, have you ever used CP/M and see it's similarities with DOS/Windows and it's differences from DOS/Windows?
