Build quality and weight is phenomenal. It seems to be mostly immune to dust too. If there were only a new model with updated specs and a better screen, maybe a bit more juiced-up battery too! I'll wait until Autumn to see if Apple has anything new regarding MBA. I'm eyeing that Surface Book. Pen, if anything like Wacom, would be a godsend for Photoshop sketching. Wacom has Companion 2, which on paper is a good thing, but it gets real hot (like real cintiq) and is real noisy when you push it.
