I have a 2011 Macbook with over 1150 full discharge-charge cycles on it that is at 89% of original capacity.
This may amaze you, but there are lots of people who work while on the go, and who can’t always be plugged in.
You only like these metrics when they cut your way. What if the metric was dollar-kilograms per hour of battery?
Here:
Why do I care? Your argument was that this was an Mac problem related to horrible Apple service. It’s not.
The application of economic principles is not argumentum ad populum.
And if I was a member of a fly species that ate shit, I probably would, too. At least, if I wanted to survive.
Unless you’re on a Trans-Atlantic flight and want to work as you bill your clients hundreds of dollars per hour, which is a very realistic situation for a lot of people. The five hour difference in battery just paid for your entire computer, paid for any dongle you might have to buy, and paid for a few hours of tech support provided by some angry guy who wants to tell you his netbook is a better computer.
And why should any of the millions of people who are happy fucking care what your idiosyncratic tastes and preferences are?
You did the calculation poorly and with questionable assumptions (such as asymmetric design, only an additional 5mm being needed for a USB-A connector, etc.). And you should tell Linus Torvalds that this difference between the 11 Macbook Air and his ideal 12", 2 pound computer is inconsequential, and that he is an utter ass for switching computers on that basis.
And the lesson, once again, is that you can’t have them all. We already discussed how USB-A wouldn’t fit in the new Macbook’s package. And note that the Chromebook Pixel is already USB-C only.
