I'm planning to get a carrying bag (most likely a messenger bag) and would like to know a few things before I do. Can I get bags that can hold bigger laptops or would bags designed specifically designed for the MB be best? Which are the reputable brands that makes durable bags that gives the best protection (and won't actually scratch the MB)? Does the product material add any additional protection or is only for my own anesthetic purposes? I don't really need a ton of space, just enough for a wireless mouse and maybe one textbook and a few notebooks, so preferably looking for more "stylish" designs. I'm only 16 so let's try to keep this under $150 . Sorry if I've asked too many questions.
