Thats a great deal. I'm sure she's going to get lots of business. Obviously this is a good argument for backing up, either at home or online but we know that's simply not going to happen, sometimes for very understandable reasons.
As for Apple's service policies, they do fall a bit short sometimes. I took my 2015 MBPr 500Gb to an Apple Genius Bar in Australia a few months ago with a swollen battery. The guy who received me at the front door said, 2015 oh, you'll probably need to buy a new one. Of course I was amazed, I said, but it works perfectly it just bulges a bit in the middle. It doesn't matter he said. We can't replace the battery on a >3 year old device because it's too dangerous.
What actually happened was that they realised that although it was a 2015 model it had been purchased in January 2016. Suddenly everything changed. Despite the manufacture date this made the device less than 3 years old and under Australian Consumer Regulations they are obligated to replace the battery and provide any works required for free. Not only that but apparently to replace the battery on this model they also need to replace the Keyboard and Trackpad which would have cost me just under AU300.00.
Funny how the process was not too dangerous when the dates shifted a little.
