I haven't added a screen protector but did just pick up a waterproof bag to use Pool side.. I am soooo waiting for the weather to warm up and I can use my NC by the pool.. btw it was only $10. on amazon and WOW it is super secure...Kwik Tek Dry Pak Multi-Purpose Case
. just slip it into bag secure the top and you can read and operate it while in the clear bag... looks weird but better than water damage from slipped drinks or fall into the water.
