The bottom line is, Nintendo knew they should have put felt lining on the insides. You don't allow plastic to run against plastic or with plastic. Hopefully when I get one the guinea pig issues will be no more

If you scratch it 99/100 its the user fault.

Nah. Not mine, anyway. I did notice there was some sand on mine one day. I was playing it on the sofa and left it on the floor. If I'd docked it, it probably would have gotten scratched by the SAND. I'm not an idiot so I just dusted it off.

I dock/undock my Switch daily and have seen no evidence of this.  I did put a screen protector on it eventually (after about 2 weeks of use), but that was more for safety reasons outside the dock than the actual docking process.

If you even look at the inside of the dock, there are protrusions on the left and right that line up with the Switch's bezel which would prevent possibility of screen scratching.  Putting the Switch in the dock doesn't require careful examination to achieve this line-up either.  It's common sense and natural.  For example, if someone doesn't use common sense/care while inserting/removing discs from an Xbox One, they're going to scratch the disc.  Now, is that a design flaw on Microsoft's part, or is it careless on the person handling the discs?

I'm actually surprised that this is the first time I see this question being asked. Folks, please think about that.

Nope. I have a screen protector though, I take mine on the go everywhere.

It likely will only scratch if you jam it in recklessly.

Regretfully, my device received obvious scratches on both sides of the screen where the device possibly makes contact with the dock. Now i'm fairly careful with my device but obviously sometimes I would slightly move the device left or right so that it would begin charging which I believe is the likely cause of the scratches. I have since purchased the Orzly screen protectors and a Dock Cozy off of Etzy and have had no issues since.  It is important to note that my device was purchased on launch day.

Yes there is but it's subtle scratches, it still bugs people with OCD. Any surface that grinds against another surface or edge is bound to leave a scratch or a mark over time. It's just physics at work. By making your Switch slightly thicker by even the smallest amount you're increasing the chances of that by removing the breathing room. There's also the element of human error of people subconsciously docking or undocking the switch at a slight angle.

I imagine that correlates directly to how careful you are with it :p
