Been using my new 15" MBP for a few weeks now and this is something I've always pondered since day one. First of all I hate using cases/screen protectors etc, I've never had any sort of aftermarket accessory on my iPhone/iPad/MBP 13" for as long as I've owned them. But the palm guard for my MBP 15" may actually seem quite useful without destroying the looks (especially the Moshi models). Main reason is because I want to avoid pitting in the aluminum due to wear and tear, but then again I've had my 13" for almost two years now and there were no signs of pitting anywhere on the surface. what do you guys think?
