Personally I would recommend A-Eon stick to the X number scheme. X3000, X5020, whatever. This clearly differentiates classic and new-gen models. In Trevor's speech he said he originally intended to use (for example) AX3000 but "AmigaOne AX3000" was a bit of a mouthful. In my opinion AX or X would be preferable; people don't usually say "AmigaOne" anyway.
