Not needing ports doesn't necessarily imply a predominantly cloud-based scenario. Some of us do use native storage for pictures, documents, Keynote presentations, files, etc... and utilize AirDrop to transfer files between Macs and iOS devices. Works very, very well for me. Probably doesn't work well for people who work with very large files (video files, RAW images, software builds, CAD, etc...) People with those applications will probably prefer the Pro line of laptops, not only for the sake of faster, more reliable wired ports, but also for more powerful CPU/GPU capability.
But people need to stop assuming that MOST everyone NEEDS that kind of power and connectivity, and that there aren't a LOT of people who use laptops for professional applications that don't require mass data transfer&storage and power CPU/GPU performance. Writers, journalists, lawyers, CEOs, executives, teachers, students, pilots, salespersons, doctors, etc...etc... Many, many professions require lesser computing capabilities, and for them, the new rMB may indeed be ideally suited.
sport watch and leather loop band, and i still saved a couple hundred. Also i couldn't be happier with my MBA. I'll probably pick up the new rMB in three years when they sort things out, has at least a skylake processor, price drops and is in the certified refurb store.
