I haven't been able to run Richard's latest image (may have = to do with eeprom updates I did)
so no idea what = 9pi does as yet.

Price and quality will be the biggest factors, as always.

Ideally, storage is where the value will reside, the actual processor
could be expendable.

ARM would allow me to start with Richard Miller's release, which I
believe to be a very sound foundation.

Thanks for any and all comments.
