I was going to buy one but after the bad press about screen quality I asked the store to allow me to see the screen before I purchased it and they (Best Buy) refused to allow me to open one prior to purchase, so I deferred. Not that it hurt their sales at all, some lady took the one I had from my hands and bought it.
Because the Switch is a console/portable hybrid it would be a good idea to put a screen protector on as soon as you brought the device.
Most people who get a new mobile or handheld get screen protectors put on (some mobiles actually come with them) from purchase but there are always some who honestly think that there is no need for the additional small expense. Usually, these people get very upset in a few months when scratches appear on the unprotected screen when a bit of forward-planning could have prevented or significantly reduced that.
Of course, dropping (the Switch is also a handheld) is not a good idea but in many cases, it is inevitable especially if you give the Switch to kids and young teens but then again there are some adults that should not be let within five meters of any electronic device.
