Great pics, thanks for posting them! How is the gain dial in terms of how much resistance to turn it to change levels? Some people had reported that the D50's gain dial turned too easily so I'm curious how the M10's dial is.
There's actually a lot of resistance, and it wouldn't be easily budged in pocket or case.
Also, part of the frame that encircles the body of the M10 goes over the gain dial, so that only the top and bottom portions of the wheel are exposed.
There's another useful bit: when you turn on the unit, you push the power switch towards you and hold. It takes only a second for the M10 to light up. But when you're turning it off, and you repeat the maneuver of pushing and holding the switch, it takes about three seconds to turn off. So less likely to have it accidentally power down by knocking it.
Of course, there's also a hold switch, which you engage by pushing the power switch in the opposite direction.
One thing to watch out for: the speed control is a switch on the side. I turned it on by accident and got a real scare. My recording of rain sounded like a ring modulated Jamaican steel band on acid.
It was playing back at 30% slower speed, and it gave me a minute of terror thinking I'd have to send the unit back!
