Just last month I finally sold my 15" MBP (early 2011) for $500 after whining on reddit, and having no chance of repair, except the apple auth. guy said, I need to change motherboard.

Also I voted this. http://www.change.org/p/timothy-d-cook-replace-or-fix-all-20...

I wish I had not sold it. :/ because for $500 I could only get the HP pavilion :/ as a replacement., you know that alone is the most terrible fact about this whole episode. that Had to use a HP lappy. :/

If I were apple CEO, I would be sending a personally signed, apologizing note to each of these customers, with a bag carrying a new MBP.

In my case it took 45% of my fortune to buy that machine. :/
