Sadly, the sharp edge isn't the only flaw you'll have to deal with. Eventually, your hinges will break and Apple will try and shove down your throat that YOU overextended the MacBook Air's screen. Who would force a screen open wider than it goes on a $1800 notebook? Hell, who would do that to any notebook?!
I am about to send back the MB and MBP that I just bought if they do not fix my UNDER warranty MBA. I am so pissed off at the way Apple has treated me. Don't get me wrong, I love the company.. I really do. But man.. the disrespect and general bad attitudes are repulsive.
