I mean, basically we could interact with a lot more hardware, support more file formats, filesystems, and network protocols, and had more high-level scripting languages. But there still seemed to be a huge disproportion where the QNX floppy was just so much more space-efficient for what it did.
I even ran the full QNX Momentics desktop OS on my home PC (a PIII 450) and it was very very impressive, way better than Linux and pretty much everything out there. Well, BeOS was also impressive with its multimedia performance, but QNX was just so much more polished and professional.
The late 90s-early 2000s was such an interesting era in computing in general - at one point I was multi-booting something like a dozen different OSes - DOS, Windows, Linuxes, BSDs, QNX, BeOS, MenuetOS.. all thanks to this fully graphical boot manager, I forget the name but it even had a built-in partition manager - and it even had mouse support! All these OSes were also quite usable, unlike all the niche OSes of today, many of which sadly can't even be installed on real modern hardware because of all the complexity. I really miss those days, it was truly a golden era of computing.
