@BooBoo1200 and Bamiga2002,
I must disagree. What you are describing will be no different than what I and downix are suggesting.
Amiga Inc., or the Amiga Community via Open Source, or a combination of both should build a brand new AmigaOS on top of QNX. QNX provides the glue to access at low level the graphics and sound card chips, the sata hd controller, usb, bluetooth, etc. Amiga Inc., and/or Amiga Community provide the look & feel, and compatibility to legacy Amiga programs, while making improvements to the overall OS functions where ever possible as well. Like mentioned before, QNX already runs on so many different CPUs and it can scale from cell phone size devices, all the way up to network servers and beyond.
I can't for the life of me see an advantage for Amiga Inc., or the community to start from scratch in building a new OS. Using QNX as a base starting point will speed development time by years, not just months of work.
