Do I really NEED a screen protector? I'm really starting to have some doubts. If Apple put so much thought and consideration into the design of the iPhone, you'd think that it wouldn't be that big of a deal if you don't have the screen protected. They would have the foresight to think, "people are going to put their iPhone in their pocket, let's make sure the screen can stand up to a set of keys, jeans, change, etc." Like many others, I've got the matte black Incase Slider, which I love. I can understand the use of a case for protecting the backside from scratches and impact. But as you also probably know, unless you have an SGP, Steinheil, or Power Support screen protector, it's likely to bubble up on the sides. It looks like crap! Why even use it?! What are your thoughts?
