2. Some of us bought the M for use as a big sensor, pocketable point and shoot. Last thing we want is to slap on an adaptor, and then slap on a big hunk of glass and metal in front of that.
Some of us bought the M for use as a very small backup body to bring along in case the primary dSLR fails, and for that use the adapter is required.
But I do agree - for general use, I have no intention of putting the M+adatper behind my 24-70 II, 70-200 II, or 600 II (well, maybe that last combo one time as a novelty!). For general use, a wider selection of EF-M lenses is needed (personally, I'd like to see a 50-1xx telezoom, in addition to more pancakes).
