Also, there is no reason in the world why the MacBook Air should only have an IPS display option. Make a MacBook Air+ or something, one step above, and overcharge me for an microLED or OLED. I don't care, take my money. Apple seems to be the only company that still sees OLED as this untouchable, expensive feature that should only be the most high-end laptops, and that is just not the case with most PC competitors in the same price categories. We don't even have an OLED option in the insanely priced MacBook Pro's yet!
I think Apple knows that many people who buy the MacBook Pros do so for the design, ports and the better 'pro' display, not always for the power, so they have to keep the better display options for the pro-line only. I am sure many MacBook Pro users today (who don't actually do heavy pro work) would switch to a thinner and lighter MacBook Air with an OLED or microLED display, no fan, and with more than enough power.
