I have always hated big bulky cases and especially hate screen protectors. I recently got a new job where I will have to use my phone in dusty environments. I'm looking for a case with port plugs and some amount of drop protection, but no screen protector. I bought an Otterbox Commuter which seems ideal, but the fit and finish sucks and the edge gets in the way of typing with my fat thumb. Does anyone have any other suggestions for a dust resistant case that doesn't have a screen protector?
