Ian,
I completely agree with your premise of different rather than better.
Its a shame some member's don't respond in this spirit, when responding to comparisons between keyboards from both the open and closed systems.

There is always something to be cleaned from comparisons.

If it doesn't interest you and you can not make a constructive responce,don't reply,which will be a much better contribution than making it a better than yours followed by the usual insults.

Gilbert.
