a lot of times when i let the magsafe get magnetically attracted to the port, it aligns crookedly (the side-butt round part of it sticking up a little bit) and I gotta push my thumb down to align it in place, flush with the machine edge. I can also do this and it will land straight but not if I'm being sloppy and careless with the magnetic attraction -- more so than the other 3 unibody MacBook Pro's I've had with the same macbook air charger). Do you think the cable is defective, the port, or what can explain this happening? thanks! This seems plausible but silly (and something that I think might be the case after trying to see it connect while holding it in the air) - the cable is so thick, it's at a weird angle and forcing the cable up. Because when I lay the cable paralllel with the edges (running from the back of my desk), I don't think it does this but I will try it out and fidget with it.
