I have an issue that began about a week after I received my 2.0ghz MacBook Pro. I was one of the first people to receive one in the first shipment. / . For the most part, my built in iSight does not show up in ichat, photobooth, or even system profiler. It's as if the thing is coming unplugged. Quite a bummer. The Mac Genius said it's likely hardware related and they'd have to ship it out for repair, but I'm a student and I can't get by without my computer for a week this late in the semester! GRR!!! Not to mention my other problem with this thing shutting down all the time... (i replied on another forum to a person with the same problem).! What a pain. I guess it's the downside of buying the first generation or a new product. It especially sucks because I got this macbook as part of a replacement upgrade from a piece of junk lemon 12" powerbook which had like 5 major repair problems.
