I too think the name 'RISC OS' is perfectly fine. All these companies trying to be 'hip' and change well established product names/their own names consistently leads to drops in profit, and the usual reaction of 'What?? Who??" from people that don't know about the name change.
RISC OS X? Stuff like that maybe ok, but please, don't drop the RISC OS.
Has anyone (castle) actually emailed/contacted Herman to ask permission (maybe donation!) of the nut device to the RISC OS community?
