I have a 10.5" 2017 iPad Pro and had a 2015 12.9" also. I also have smart keyboards for both machines and the (older) Apple pencil. To upgrade either machine, in addition to the iPad, I would have to get a new pencil and smart keyboard, so I decided to get the 2017 12.9" machine on eBay -- don't have to get a new keyboard or pencil, and thus can get the near equivalent of a 2018 12.9" iPad for 1/2 or 1/3 the price. I looked at the new iPad Pro's in the apple store, but it just doesn't seem to me that it's worth paying so much for very incremental improvements that will not actually make any difference for me. No doubt Apple makes mostly good products, but why do they make us pay so much (about $300 in this case) to replace accessories that we already have?
