Well, as many as you guys already know the hinge of the uMBP, 15" specially, are too loose for most of us. I received mine Wednesday and noticed that when I lifted the laptop to take a picture during the initial setup. I called apple and scheduled a Genius Bar visit for today. There I went, was helped on time and the game started. The Genius gave his "knowledgeable" opinions to cover apple's ass and not take the return, and I gave them many examples why it shouldn't be loose like that. At the end there was nothing they could do to tighten it up. Replacing it would only waste may time, because all of them are like that. Now I have a very expensive computer which I can't return without eating the restocking fee. I believe we are gonna have to live with that. I found a website called www.fixthehinge.com which I would recommend whoever has this issue to sign the petition. If you guys have/had any experience to share please let me know.
