The Touchbar was my daughter's favorite - an Emoji keyboard. It also did a lot more - bringing up manpages in the terminal, having app-specific buttons (no need to hunt down the Zoom window to mute). People wanted an ESC key and they got it eventually. I couldn't care less about function keys. I get it was very expensive for the little if offered, but, still, it's still useful. More useful than F1 to F12 ever were.
Magsafe is nice from a safety standpoint (I have a kid and work from the couch sometimes), but with all-day battery life, what is the use of it? On my desk, the Mac is plugged into power, two external monitors, ethernet, keyboard and trackpad with a single cable, as God intended it to be. That's 3 free USB-C connectors for anything else (such as the external storage) and there is one power brick that lives in my backpack along a pair of US/EU adapters for when I need to travel. With USB-C power, it was nice to have the Dell and the Mac sharing power bricks when needed (if I said that 10 years ago, I would laugh myself out of the room)
I like the replaceable battery, but I miss the touchbar and actively dislike the reintroduction of Magsafe.
