Hello Guys; Yesterday I bought a North Face, Hot Shot backpack because of the good quality this brand provides and because I needed a bag with a laptop compartment. The thing is, I used an incase neoprene sleeve(the mbp version) for my macbook air into the laptop compartment of the Hot Shot bag today and when I took it out in my history class, I felt like if the lid was quite 'Sticked', since it was harder to open the lid. (thanks god im using the cover that came with my mba everytime until i get the screensavr or shagymac) Basically, can this spoil my machine? Also, instead of using my mba in the laptop compartment which is in the side of my back, get instead use a hard cover book and then my macbook followed by my bunch of books i carry everytime to decrease the pressure exerted in my mba since my back is not completely straight when I walk. Thx in advance!
