Mine's brand new and I want to keep it that way. I'm scared to death of scratching the aluminum, wearing out the trackpad, or even just smudging the screen. I use a Power Support Anti-Glare film on my iPhone and I see that they offer the same product for MacBook screens. Also, for the laptop's case, I was thinking about getting an Invisishield protector. Does anyone here use either of these products? Or, do you have any alternative suggestions? Thank you for your help, guys?
