Me. Macbook 12 is one of my favourite machines ever. Every Thinkpad feels super heavy and bulky in comparison and I don't want to use those. I value mobility above all else. If I want performance, I have my desktop machine or cloud for that.
I have my desktop for serious typing and my laptop for a mobile workstation. Sometimes I need to work while visiting family or when going to conferences, and I need a decent keyboard, battery, and performance to do so.
If I want thin, I'll get something like a MBA, a tablet, or my little Lenovo Yoga (11"). But that's not enough for me to get work done on the go, it's mostly just barely good enough to take notes and watch videos. I need something capable of compiling decently large codebases and 3D rendering, and no MBA is good enough for that.
