Question: what is the difference between an air and a pro?
Answer: Apple upgraded the Air to a Retina Display with True Tone technology in 2019. They both have 13.3in LED-backlit displays with IPS technology at a resolution of 2560x1600 making them 227ppi. The only difference is that the Pro boasts a 500nit brightness level and wide colour (P3), with the Air on 400nits and sRGB.
