There's some pretty basic form factor changes that can go a long way to just eliminating portable units, i.e. these new U shaped designs.

Wonder why there's no "n" designs for obstructive light. Regardless, there's no reason for portable AC, even duo hose ones due to length limitations on hose before inefficiencies. More effort into easy to install window / split units please.
