I also have a 2016 12" Macbook and love it. It's my full time personal machine, having replaced an older iPad and MBP. I love the form factor and weight, but I like it more than an iPad due to having an actual keyboard and ability to run real software.

As you say it's getting a bit long in the tooth and I've been lamenting that there's really no replacement for it. I've been holding out hope that apple silicon will change that.
