Does the Note needs a screen protector (SP)? Personally I would say hell yeah but to each their own. At least with a screen protector, you get a scratch, you can always replace with a new protector. W/O a SP, you risk your device in getting scrathed up. Plus, with today's SP, you will likely not notice the difference. Always err on the safe side & better to be protected than not to be. Plus, resale value is higher if your phone isn't all scratched up. That extra $15-$20 for a SP goes a long ways.
