My personal machine is a 2014 13" MBP. I haven't needed to replace it, but that time is coming relatively soon. I've been contemplating just going with an MBA instead of a MBP for my next machine. I don't do so much heavy lifting that I think I need it. It's a weird feeling because I think of myself as a "power user" and in the past that always meant getting the most computer you could afford. Now I'm not so sure...
