The reason is simple. I blackout in my lofted bed of my fraternity house with my laptop, I woke up with my room mate asking me what I did to my computer. The lcd screens cracked, APP wouldn't fix it. To fix it it would of cost $800, plus I think the mother board on it got screwed up. So after I transfer my data to my new Imac I plan on disecting my poor old macbook. Well I just figured I share a story and a good reson to get another mac.
