I plan to buy a Macbook for college in the coming month and I'm curious as to how to fully protect it. As of now I want to get an Applesac sleeve, Moshi Palmguard and Clearguard. I don't want to get a special laptop bag because I don't want to spend a lot of money. Is there anything else that I would need? I don't plan on carrying it around often, maybe to the library but not to class everyday. It would just be in my regular old Jansport backpack. Do you all think I would need a hard case or a screen guard? Maybe invisishield? This is my first laptop after using desktops my whole life so I'm kinda new to this
