Since my MacBook is new, I'm very careful with it. The slightest knock panics me. Just wondering what the wear and tear is like? After the mishap today with it getting picked up by the screen, I'm being even more careful. I haven't dropped it, just banged it slightly when putting it down on a table a few times. These are minor and can be ignored, right? I'm going to be taking this to university, once I've bought a sleeve for it, hence me wanting to know how much it can take, wear and tear wise.
