i just got my macbook TODAY, and while I was installing world of warcraft, i picked up the macbook, to bring it to the sofa. while i was picking it up, i tilted it a bit (maybe 40 degrees?), and the CD started spinning (or at least sounded like it) like a crazy person, and i thought the computer was going to explode (it sounded like that). everything seemed ok though, until I inserted another CD. the macbook now makes a cracking sound (3 cracking sounds actually), and if you hold it you can feel the "cracks" below the cd-rom. I don't remember how this sounded before I picked the macbook up, so I can't really say if this is normal or not. that's why I'm asking you guys, is this normal? should I take it to the apple store? I can't afford to "lose" my computer for even 1 day since I'm in school and use my computer every day for school work.
