Richard, you are right, the eventual goal is no ports… and no wires. When I was consulting we were doing concepts around this for the big chip makers back in 2010. You can imagine a phone with no ports, wirelessly charging, wireless input and output. It is not a huge stretch of the imagination noting the trend as you clearly pointed out. We are almost there. You can now wirelessly print, use BT for keyboard and mouse, synching audio to video over BT is still hard but will get there (this may be a problem with their buds FYI, some phones have wireless charging, BT audio has a lag, and unless the video is paused and the lag is matched within a microsecond you will detect a lip synch effect). Obviously waterproofing, durability, and construction all gets easier. It is hard to make the 3.5 waterproof from my experience. Ironically it is easier to make a speaker driver completely sealed (with they obviously did here) with s combination of internal seals and hydrophobic grille cloths…
