this is one major reason why i dont think they'll go portless on the iphone any time soon. apple lossless & hifi lossless was *just* added this year. if they go portless even within the next 5 years, they don't have any ground to stand on when promoting new features, since we wont know how long they'll actually be relevant for.
the watches going portless is fairly meaningless to everyone who ever owned a watch, except for the few device hackers who managed to interface with it. i think they'll get clever and find a way to leverage the new wireless communication tech. for the rest of us, no hardwire connecting to the watch didn't matter since apple didnt provide us a way to do anything with that data port, sadly including just being able to restore it ourselves.
portless on the iphone and their other devices really just doesnt make sense from a number of standpoints, and lossless is absolutely one of them. they did, after all, have to spend time and resources to get almost the entire AM library into lossless & hi fi lossless. silly to bother with something like that, advertise it, and then just get rid of the means to use it.
