I have a 2011 Macbook Air that the new iPad Pro beats in all/most benchmarks many times over. While that interests me a lot, this laptop from 2011 runs the newest OS X 4 years later, and has gone through 5 OS upgrades from Lion to El Capitan, and it is still working like a new laptop. I wonder if the iPad Pro will be able to hold up and still be slick-fast by iOS 13? If it does, then it is fair to make this a good primary computer, but the way the AX processors have grown, this iPad Pro may not last two upgrades before it starts to feel old. Thus, not worth its price. It will also be pretty sad that the iPad Pro cannot beat a Macbook Air in longevity despite its reputed processor speed. Where do you think the performance of the A9X project 4 years from now?
