Surely the thing that makes such a development so fantastic is not any perceived advantages of one branch of the OS over another but that the platform we care for has a future - no new hardware = no future. It may be a purely psychosocial difficulty but no platform can survive under emulation only.
For myself I don't care which branch we all use as long as there only ONE branch in general use - better still; the best of both merged.
All the ARM computers I own run ROL OS's but if they all ended up soft-loading ROOL OS's that would be fine by me assuming that's the branch everybody else is using. (or vice versa)
After having no future, which the above news hopefully addresses, by far the worst thing for RiscOS is having all this business with two OS's.
