okay, i am in no way complaining, just thought i should warn some people I had my macbook in my backpack. the same place i store mechanical pencils. it turns out those little pieces of lead can stick to the magsafe plug. no biggie, but i was startled when my magsafe plug was crooked, and i looked to see like 8 teeny pieces of lead magnified to it. All it took was some rolled up tape and an eraser to erase the marks they left, but it was startling! if you use your macbook in your backpack, try to leave the ports facing up.
