I consider non-merged SD and main memory a good thing - I like knowing where the stuff is.
The rest of the problems seems to be something they can resolve in a firmware update

If you email them directly and inform them about it.
Since this firmware took care of (hopefully most of) the random stability problems and various models interchangeability, the next update (if they plan one) might not take so long, if all they need to do is small bugfixes.
