Ours should be coming today, I know this is optional but what do most do?Are there any big disadvantages, im thinking just the case will be enough? I've had the same Switcheasy screen protector on since getting my iPad 2 Animal Cases. Last long, hasn't bubbled, shows little scratches (it's plastic so scratches will show). An excellent add-on. Yeah I have one on mine. No problems with it and fits the iPad fine with no lifting even after a few months。 Thanks for the responses.How does it feel to the touch. Does it add a lot of friction?
