Another two features, suggested by John Lee:

- high eyepoint viewfinder for glasses wearers

- builtin diopter

Both have been done already so again, it's a matter of collecting the state
of the art and implementing them together.

The M10 is likely to be larger than the M9, so may be there will be a
resurgence on used M9 sales :-)
