Earlier quoted context omitted.
You can get the function keys with the Air, which has the same internals as this Pro.
The air is missing the active cooling. The next upgrade that puts apple chip in the 4 port pro would be the ideal version to purchase without a Touch Bar impacting usability and battery life.
You say this like it's a negative thing. For me, personally, computer fan noise is uniquely aggravating. I wanted to buy the 2015 Macbook specifically because it was fanless, but decided against it because a x86 CPU trying to run in that fanless form factor essentially made it a $1K netbook. Now that we're seeing the M1 MacBook Air rival the 16-inch MacBook Pro from last year in an extended CineBench test (even through Rosetta!), it's a different story entirely.
I'm not saying active cooling doesn't help, obviously the Air is going to thermal throttle in cases the Pro wouldn't. But I am saying that the new chipset needs active cooling a lot less than the old one did; not just cause it's RISC vs CISC but its also 'cause it's TSMC's 5nm process vs Intel's 14nm one.
Also, I'd give up on the hope that they'd get rid of their stupid meme bar on the Pro. They seem committed to it.
