I definitely see the appeal of newer options and though I'm probably in the minority on this I see a lot of appeal to the original headsets as well. Not totally on topic but thought I'd share some "alternative" reasons to keep the factory headset in hopes that it helps a few more stay out of the trash!
Cosmetically the original style headsets are one of the features I remember most clearly from driving Toyota's in the 90s and I definitely enjoy that connection. I spent a lot of time learning to quickly tune the bass/treble/balance/fade without looking all those years ago and it would be a shame to not put those skills to use

I also really like that the 80 can be a screen-free zone if I put the phone(s) out of site. Not running nav on the headset also means one less device to manage connections, updates, etc. for. I probably value a lot of this more because I'm a programmer by trade and like stepping away from management of IT when I can.
Another way of seeing the appeal of keeping the original headset aligns with that of Vinyl collectors who enjoy the experience that the format offers. For instance I've really enjoyed rotating my old CDs and cassettes through my 80. These older formats encourage repeat listens to the recordings in the order they were recorded and it's fun for me to revisit music the same way that I experienced it a few decades ago. Without the 80 they'd never get played and would likely have been binned (many were over the years). Interestingly younger folks seem to be leading the interest in vinyl, cassettes, film cameras, etc. but I think anyone can enjoy them in the right situation.
I also have a bluetooth adapter and listen to spotify, podcasts, take hands-free calls etc. in the 80 so I'm not giving up a ton there with the old headset and as my phone improves so do most of those functions.
Throw in some new speakers, replace the stock sub with an under-the-set style enclosed sub and enjoy decent sound quality and for a few of us at least, a better experience while driving our 80s.
I'll continue to read and appreciate the builds with the new headsets, backup cameras, built-in trail maps, etc. but hope to see a few enjoying the old headsets out there too.
