Bought one back in May and I haven't got any of the problems listed on the video, thankfully, but I do have "scanlines" on the screen. And I say "scanlines" because they supposedly don't happen on LCD screens, but what I see produces pretty much the same effect: thin horizontal lines, almost traslucent, that appear when there's motion or when my eyes move across the screen. It's like flickering, but not as annoying, and they vanish after 30-60 minutes, or at least they soften, but the first 15 minutes are just unbearable.
I'm sending my Switch in for repair next week.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
