any of us still missing those?
needless to say that it kinda sucks when a new device forces you to buy new adapters / peripherals, but in the long run, is this really an issue?
Anyways, your examples are not exactly the same as this situation. In the cases of removing the floppy drive and CD/DVD drives, it was upgrading one technology for another which was able to hold more data, was a more stable medium than the predecessor, and was generally more reliable. The 3.5mm->bluetooth was not an upgrade in stability or reliability, and the ethernet->wifi change was not an upgrade in anything except 'mobility' (but systems with ethernet jacks at that time typically had wifi too, so, again, it was a general downgrade in functionality).
I still miss having a dvd drive every couple of weeks, when I want to watch a video that isn't on a streaming service.
I still miss the serial port when I'm fiddling with bits of hardware (and my old graphing calculator).
Parallel port we're well shot of though.
Back in the day serial and parallel were very useful for interfacing to real world machines. Now everyone uses a simple linux board like an rpi, but in the interim it was seriously inconvenient to interface. USB1 is absolute rubbish, USB2 not much better.
heck even if my laptop comes with a ethernet port, i still couldn't use it at my workplace.
In the case of the ports you've mentioned, there were other improved connections to move towards. The blutooth headphone is not improved over the 3.5mm cable unless you are so vehemently opposed to the idea of a cable that you would live with its shortcomings. Market leaders like Apple and Samsung have made investments into this market (beats, for example), and to try and dominate market share are extorting their users into buying extraneous, disposable accessories that aren't an objective improvement of existing standards, all while parading the recycled content of their latest 128gb dual core laptops.
