Excellent, detailed review.
This captures the key problem with the MacBook Air well:
"This is most obvious when looking at text, where the Air's lack of sharpness results in blurry shading along the edges. Thus, we would absolutely recommend a higher resolution display for those of you who work with and look at text all day long."
I'm typing this on an earlier MBA and the text flickering in and out when scrolling is horrendous! It's especially hard to deal with after spending time on an iPad. The MacBook and MBP screens are much better, very iPad-like!
OTOH, the tapered large palm rest is great on the MBAs! The MacBook's is too small, while the MBP's is smaller than the MBA's and a rectangular, gotcha front edge. The MBA's keyboard also doesn't make as much noise as the 2017 MB's!
What's really needed is a 13" MacBook with two ports, Retina Display, and tapered front edge!
