John mentioned the up-sizing based on THAT rumor photo - which would make
sense if they were to include a larger LCD - the top plate limits the size.

Regardless, I am really not that interested in M10 speculation per se. I am
more interested, as a techie, on how desirable and how difficult it is to
make something like the one on my wish list,
