My sibling uses an air - built and sold one company, doing the same again with 8 digit funding. He could buy any computer he wants. He chose an air. This is unique a bit to tech world, my piece of this in IT side is not the SAAS tech directly and old IT they don't work so well so I don't buy them.
The upside, he handed off his huge tricked out machine to me. I think especially for folks who are not in one spot (ie, staying with a partner, vacation home etc etc) it works fine.
