It all depends on what you're going to do with your Switch.
If you're planning to use it as portable console then you'll just have to buy a charger which will not require to put the Switch in it's dock each times, so no problem.
But if you're like me, and you're going to use it with an external screen then there are a few problems.
I was first expecting to let it in it's dock without taking it out except for rare occasions, but you have to keep in mind that except if you're going to buy a lot of accessories, for example, you'll have to charge your playcons. And to charge them, if your dock is put with your others consoles in a place not that easy to reach, you're going to take off you're Switch, put the playcons on it put it back again until you play next time.
Another thing : you can't totally switch off the console using the menu. So once again, if you want to power it off you'll have to take it off the dock, switch it off and put it back in again.
So I'm someone like @sir adelaide described. I'm really careful with all my consoles, but even after having bought a screen protection, I really dislike this dock as you have to search the right place for the Switch to be well connected and for that, you move the console int it's dock a few times.
I don't have any scratch yet, but I'm sure if they don't release an adapter to connect the console to a screen without the dock, or if I don't buy something to charge my playcons without having to attach them to the Switch, there is bound to be some scratch soon.
