I bought my mbp 2010 at the end of last year. I had to go to apple store again and again to get it fixed. Here are the parts that have been replaced: power adapter (couldn't charge) mother board (couldn't turn it on) screen (air bubbles on it) I think I got a defective product. I spent a lot of time at the genius bar and could not use the machine for over two weeks which caused a lot of inconveniences. I am worried this will happen again and again. I called the customer service and asked if I can get a replacement without a success. What can I do?
