I upgraded from a mid 2012 13” MBP upgraded to within an inch of its life to an m3 Air 15”. I’ve loved my old mbp for years, but the increased size of the 15” display makes it better for me. My vision continues to worsen and I’m not getting any younger. The thinness of this machine makes up for the slightly bigger bulk from the larger screen to me, at least compared to my 2012 model. And the weight is ridiculously better.

Continuum was ok, but Motorola’s Atrix 4G had a lap dock even earlier. It was an outdated version of Ubuntu, if I remember, but it worked. I still miss WP though.
