I need iPad pro right away, but iPad pro 2018 still powerfull based on geekbench, iPad pro 2020 with Lidar is incredible but a little worried about the A12Z because it defeated by A14 on iPar air. And now iPad 2021 had just released with M1 chip. I just wanna make the best decision with possibility of price drop on iPad pro 2020, so a few months later i can upgrade to 2021.
