Hey all, I'm getting the new 15" Macbook Pro (Base Model) anytime now, and will be using it for many purposes, such as Image Editing (Mainly Photoshop CS5), minor Video Editing, watching videos (DVDs, 1080p YouTube, etc.), and the casual gaming. Now there are two upgrades available for the screen: the hi-res anti-glare or the hi-res glossy. I would like to ask if first of all, in relation to my above usage, will I need an upgrade at all? And if so, could anyone please state real-world changes in how the screen looks to the user. And if I should upgrade for these purposes, which screen upgrade should I purchase? Thanks in advance.
