Handling the camera in a store in order to make excuses as to buying one or not is not even close to being a review.
I earn a great living with using my M240 among other cameras for work, I handled the M10 for about an hour and ordered one. For me it is a no brainer, two stops higher ISO range alone is worth it and besides it is not that much to upgrade, $3,500 is pretty easy to come by in my business.
You need to actually own and use the camera to create what the photo enthusiast forums seem to love to pass the time reading, gear reviews.
