I know this seems like a really stupid question but how sturdy is the new macbook?? The only reason I ask this unpopular question is because I have a backpack that fits a 13incher (Hershel backpack) also filler with a lot of school bag...like my backpack is very heavy and very full... This lead me to question whether this 1500$ computer will be safe in there. I carry my backpack all day long with all my heavy books, a lunch and a water bottle. The bag is kind of tight and I'm just scared... should it bend? Should i look for a backpack that fits a 12inch (instead of putting it and have it move a little? am i overthinking this?
