As you know, I was as concerned as you about the reported reliability issues. So much so that I have kept my M10-P so far as a backup.
I have now had my M11 since March 14th. I have shot multiple images every day these last almost two Months. I know that is not a long time, but each day the camera is turned off and on multiple times, and I have taken hundreds of images with it. I have 3 VM lenses (all with my DIY 6-bit encoding on them), and two leica lenses (one with factory 6-Bit encoding, and one with no coding). So far the M11 has performed flawlessly. It does have the latest 1.6.1 firmware installed.
My other big worry was 60 mp with no IBIS. Even with my problems with essential tremors (controlled mostly with drugs), I am not having more issues than I did with my M10-P.
I am very pleased with my M11. It is a valuable upgrade in so many ways. I think I now have enough confidence now to go ahead and sell the M10-P.
