Not the only one. If you purchased a MacBook Pro from 2016-2020 there is a good chance you may have convert d most of you Older USB gear to USB-C. But there are very expensive audio gear that sometimes cannot be replaced and/ or “just” use converter adapters etc. Converters sometimes does not do the job.Am I the only person who doesn't want/need a single USB-A port? Would love a hub but I switched everything to USB-C years ago.
If the new MacBook Pro just had “One” USB-A port also, it would have added great functionality for audio creators. But Apple believes “just” put a USB-C adapter will do it, but not always, especially for audio. Making the Audio 1/8” port through-put (in and out) like the old MacBook Pros (like my MacBook Pro 2010) would be ideal also.
Apple “tried” to move the industry to change, but it didn’t (or was too slow). “A lot” and I mean there is a lot of good gear that manufacturers did not update drivers nor ports, so we got stuck sometimes buying newer gear that was not as good.
Such is the tech field, but if manufacturers followed the change then “Yes” there would be more users who don’t need USB-A ports. I would prefer, but USB-A ports are still here and maybe here to stay (at least for some time still).
