Hi Nancy and welcome to the Forum!

As Junior has said, it is a personal preference, some don't like them at all. Having said that, I do have one myself and I can tell you it has saved my screen from at least 2 scratches. There are different protectors you can get also, anti glare, Matt finish there's even one which is like a mirror when viewed from the side, this one helps if you use your iPad in front of others and don't want them to see what you're doing. The choice is yours.
