My Macbook has the StainGate issue. By now, the entire screen has become stained and can no longer be used sensibly. Unfortunately, the Macbook is no longer eligible for a free exchange. Apple wants to charge approximately 850 Euros ($1050) for service. The question now is: What to do? The performance of the Macbook is actually still sufficient for me and the battery is still good (450 cycles, 85%, changed two years ago). Should I replace the screen or buy a new machine? In case of a new machine, I would choose the 13,3 rMBP TB, as 15,4 was always a little to bulky for my use case. Any advice?
