Anyone else have a squeaky hinge on a Rev C or any other? I hear all the talk about lose hinges and broken hinges but the absolute only worry (and it is not a big one) I have about my magnificent two month old Air is the squeak it makes sometimes when I open it up. I suppose that a too tight hinge could lead to a broken hinge but it doesn't sound like the kind of squeak that could lead to breakage. But who knows. If I open it very slowly it doesn't make it. Eventually I'll probably take it in, but not for now. Everything else looks and works too well. Would appreciate hearing from others who hear from their hinge.
