I'm thinking of buying a C2D MBP, but I like to try to retain the value of whatever electronic equipment I'm using by getting a case or some sort of wrap for it. I.E.: My iPod, has a Contour Showcase around it...Always...My PSP has a Logitech case around it, what can I say...I like to maintain the possibility of a high retail value. So to those of you with naked MBP's right now, I'd like to know how long you've had it in your possession, and what, if any, tell-tale signs it is starting to show. Preferably, I'd like the opinion of students who carry their MBP's in their backpacks as that is likely what I will be doing. I keep worrying if I should get an Invisible Shield for the MBP's body and some sort of screen protector to protect the glossy screen from the keyboard, and an iSkin ProTouch to protect the keyboard, but then I read threads about how durable the MBP's body is and, needless to say, I'm pretty confused. Do I need to protect this bad boy or not? Thanks!
