with a screen protector youre fine, but the bent dock issue isnt nearly as wide spread, and its easily detected or resolved.
If your dock is bent enough nintendo will replace it for free as it is a manufacture defect.
just take a look at the dock before using it. If its too bent youll want to apply a screen protector or a sleeve before using the dock. (if the system comes in a foam sleeve that will also work as a temp dock sleeve). You can also send bent docks into nintendo for a warranty replacement.
Other wise you should be fine!
