Have you tried some sketching with the connector on the side, opposed to the hardware volume and power keys? This way, the Jolla would be easy to handle, as the large plug would not be in the palm, nor on fingers holding the Jolla on the left side (if you are right-handed of course). Additionally, it would keep the phone thin, wouldn't block the micro-USB plug nor the microphone, and would be easy to put in a jean's pocket.

Or on the bottom, but the orientation may be an issue for some uses.
