Got my MacBook Air delivered today, opted for silver over space grey because it is more classy imho.
Some initial impressions - Keyboard is what impressed me the most, coming from 2015 there is less travel but keys are more sturdy and clicky. Keys in 2015 feels wobbly in comparison. Speakers are another major improvement with real bass coming from those tiny speakers. Bezels have become minimal and screen feels more immersive. Resolution wise I felt text to be smaller then 2015 I had, so there is more real estate here. Form factor imo is better then Pro as it feels more dense. Overall fluidness is better but not by a whole lot margin..
Forgot to add Touch ID, nice addition for those already in the ecosystem.
