Seems to have crazy performance for a device under 500 grams.
But the iPad Pro 10.5 already had crazy performance compared to my good old iPad Air 1. I'll probably try to get a used or refurbished iPad Pro 10.5'' / 256 GB now for €500 - €600 instead of a new iPad Pro 11'' / 256 GB for over €1000.
Performance difference aside there aren't many improvements to the 10.5'' (almost same size, weight, resolution, camera, battery capacity, both 4 GB RAM, 120 Hz True Tone displays, 4 speakers...) and I don't want to lose the home button, the headphone jack and a rectangular display (don't like the rounded display edges of the new iPad Pro).
