Am especially interested in how well the RRS grip works on an M10. I just did a test shoot of an M10, and most definitely like this camera; however, it was a bit awkward holding the camera when switching back and forth from landscape to portrait, so I thought Really RIght Stuff (RRS) might help. I use L-brackets on two Canon 1-series bodies, and the L-bracket on the left side of the body is easy to grip whether shooting landscape or portrait. Also, RRS has a hand grip that mounts on the right side of the body of the M10, and would love to hear from someone who has the hand grip to see how well it works.
