I want to upgrade to a 15" MBP next week. I have a 13" glossy atm. My day job is a digital designer and I spend all day in photoshop, seeing as I use an external display when at home I love the idea of having a matt display for my notebook when at work/traveling. BUT I've noticed with the matt display comes a higher resolution, will this become an issue for me?! IE pixel size etc?? I'm a bit confused, thanks!
