Hi!
Nice review -- I posted something similar when I got my 13" MBP. That was 4-ish months ago, and my opinion is just as positive.
I've not been a heavy user of the touchbar, but there's one thing I always use it for: phone calls.
If you've got an iPhone signed into the same iCloud account as the Mac, you'll find your Mac rings when your phone does, and you can answer calls on the Mac. The sound quality's really good and the microphone's far better than the phone on Speaker.
Answering the call can be done on the touchbar, after which it shows caller information. It also has a Mute button which is great for long conference calls. Much easier to tap the touchbar than interrupting what you're doing and clicking the on-screen buttons.
Actually, when my Mac's around, I find myself making and taking calls via it in preference to using the phone directly.
