this is consistent with about everyone. The screws you see on the port side of the macbook, are just for looks and not really screwed into anything. The screw that hold the casing to the rest of the computer, are visible when you remove the battery, on the inside. Next time you are at an apple store, check out the macbooks, they all have it goin' on. I noticed this as well a few months ago, and was pissed.
