build OS5 on QNX, why? QNX is aready a very good os with out anything "built on it", this is just retarded.
This comment really show that the retard is you, first that is like saying to apple: "Build macos x on top of BSD why? BSD it´s already a very good OS" and all we know how more good and different is Macos X from BSD.
And second QNX it´s basically an embedded OS and the UI part is not as developed as any of the mainstreamed OS.So if you get the QNX kernel and put on top a good GUI and API (ie Amiga) you *could* get a even more good OS than QNX.
said this, yes, QNX is really good together with BeOS and AmigaOS the best OSs ever made IMHO
