I was actually worried about the Q button as well but in real life, it's basically a non-issue for me.

I'm left-eyed, that's maybe why the Q-button is a bigger annoyance for me. Because my thumb happens to be a bit further to the right, usually right on that button. Also, touch AF doesn't work for me... it becomes "nose AF"  

Also: just found out that assigning AF-ON to the Q button does not solve all issues: because it overrides the setting of the AF/M switch. Even when set to M, AF-ON triggers the AF. Duh...
