Used to have a case for my Focus but took it off when my daughter pointed out how cool the Focus looks without a case (I had forgotten about that). I didn't have a screen protector, but one day I had my phone on my lap and dropped a set of keys on it, nicking the screen in the process. Unfortunately the damage is close to the middle of the screen and I can't sand that off or anything, which stinks. I put a clear screen protector to prevent future damage, but it sucks having that nick in the middle of my screen.
