Well if we get no CPU improvements (less than 10% between a12x and a12z), and only a ram improvement of 6gb in some ways the iPad Pro line is disappointing when you can get 3gb a10 ipad for $249 to $330 depending on sale prices. (7th Generation ipad has 3gb of ram, the 6th generation has 2gb of ram but the same cpu.)
Yes the iPad Pro is better, but the a10 is almost 1300 days old and the a12x is over 500 days old. I was hoping for something a little better given the time.
I bought a 7th Gen iPad with 3 GB RAM and 128 GB storage and 4G LTE in December for the wife. Truthfully I was a little apprehensive about A10. A10 works fine in my current iPhone 7 Plus (also 3 GB), but I was unsure about the iPad with its much larger screen and desktop class web browsing.
In reality though, that A10 iPad is just fine, and the Apple Smart Keyboard for it makes it a complete device. Side by side with my A10X iPad Pro, I can notice that the A10 is slightly slower, but overall it's quite decent. I wouldn't have bought it for myself, but it's more than sufficient for my wife, who was using an A8X iPad Air 2 before with no problems. With 3 GB RAM in the A10 iPad 7, I think that machine will last her a good 5 years. Using Geekbench as a gauge, for mainstream usage I think any iDevice with a multi-core score of 1000 or above and 2 GB RAM (iPad Air 2 or iPad 5th generation) is usable, and any iDevice with 1400 or above and 3 GB RAM (iPad 7) is actually quite decent. And any iDevice with a score of >2200 (iPad Pro 2nd generation) is downright fast. The 3rd/4th generation iPad Pros with A12X and A12Z with scores >4700 are blistering fast, but for browsing it's really only a small incremental improvement over the 2nd generation iPad Pros, since the latter already quite fast for this purpose.
Regarding pricing, one big reason for my getting the iPad 7 Cellular was because of cost. I managed to get with 128 GB for just CAD$500 brand new from my carrier, which currently is just US$350, no contract. And after using cellular on her iPad, I want to get cellular on my next iPad Pro. However, if I'm spending that much money on an iPad Pro, I'm thinking I want to get 5G. If I were going to get a WiFi-only iPad Pro, I'd be purchasing now (or at least once the new Magic Keyboard comes out), but since I'm considering a cellular model, I may wait. Decisions, decisions...
