Well, you forgot the various higher-tier kinds that need to be permanently installed. Traditional central ducts, ductless mini-splits, radiant cooling, etc.

Also, I'd argue that opening a window and turning on a fan is just as good as portable AC with hoses in many climates while being much, much cheaper.
