Just like an auto
I too have had problems with an Apple product. I have a 15" MacBook Pro. In one year I have had the logic board replaced twice, the LCD replaced twice and the battery once. Is mine a problematic machine? Definitely. Have I taken it in at the first sign of trouble? You bet. But in my past experience with Apple products this is not typical. Will this keep me from being an Apple customer? No. It's not as if other laptop manufactures don't have their share of problems.
What I think is funny is how all the signs were there that you had an issue but didn't do anything ahead of time. You waited until catastrophic failure and then cried about it.
If it was an auto that started to show signs of trouble I doubt if you would have continued to drive it and wait for it to break. You would take it to the garage right away. That is what you should have done with the MacBook.
It appears that Apple giving you a new laptop wasn't satisfactory enough. A little spoiled, eh? Next time you have an issue with an auto see if you can cry your way into a new car after you ignored signs of trouble while driving it.
