sa110>That is because in the *old* days Acorn did all the OS - hardware drivers included. ROL don't (which is what I said earlier).
They may feel confortable about delegating someone else to do the drivers - but this takes the OS development out of their full control. When all the drivers are present and everything works then the OS is complete - not before. The fact that a part of that work has to be done by an organisation *other* than ROL is neither here nor there.
From ROL's perspective having an emulated platform *only* would eliminate *all* the hanging round on others to complete drivers. They could just "ship" the RO product the moment their internal and beta testing had finished.
