I used my 17 inch Macbook Pro everyday for six years. It would still be going if not for a failed GPU. I did take it apart hoping it was dust and heat causing the problems but no it was a fatal hardware fault. It's now just a shiny aluminum lump. There's nothing worse for electronics than heat. The damage is cumulative but nearly impossible to notice until it's too late.
