I got my Touch yesterday, and I don't care how sturdy it is, it needs a screen protector. IMHO, screen protectors should be a necessary accessory for the iPhone or Touch.
I think that cases for the iPhone and Touch that don't have screen protectors are absolutely useless, I mean, wouldn't it be common sense to cover the ENTIRE device (excluding the external buttons and the dock connector) to protect it? And some of the cases that don't have screen protectors are like $25-30!! It's crazy.
