But as Acorn also demonstrated, single ownership of the OS did /not/ guarantee the future. Speaking personally, I bought an Iyonix on the basis that Castle have demonstrated a commitment to the platform both in terms of length of time as a supplier and, even more importantly, willingness to commit money to development of new hardware and the technical ability to deliver satisfactory machines in volume, and support them. This is not to deprecate the efforts of ROL or A6, or anyone else for that matter: anyone looking to develop the platform deserves support. But the OS fork does worry me, because it means loss of focus and inefficient use of scarce resources. The ideal scenario would be a unified OS and a diversity of hardware suppliers.
