You beat me to it and I'm glad you did because your review had the most important details of all the reviews I read this morning Mostly the ones I read stopped at "front-facing display for selfies: killer feature."
I don't want to know how much I've spent on GoPro cameras and mounts and DJI drones and hand-held stabilizers. My closet must have 20 items I haven't yet eBayed or I broke.
Anyway, your review spared me from buying one more thing and be happy with the GoPro 7. I thought about the front-facing display and at first I thought I'd like it while doing something like cliff jumping, but I'm not going to be looking at the display when I do that.
