Teardown video is good, almost on par with something from iFixit. Maybe a bit less precise/well rehearsed but that is OK.

Also like that it's just a normal engineer doing it and not some marketing person/"advocate". Makes it seem much more relaxed and well, normal. Chill dude sporting some tats and speaking normally as he pulls something apart shouldn't be something amazing or anything but it's just such a rarity in todays carefully groomed public image machinery that we see from big companies.
