@tim did you ever take a look at that unihertz phone I linked you too? Proprietary android bits aside; just talking about pure hardware and aesthetic. Its very much in that same blackberry tradition, screen aspect ratio and all.
I must confess ive though it wold be really clever as a phone mostly from a termux being super usable on such a device-perspective.
I really wish I had exposure to the Blackberries before they start chasing the iphone. They were doing some really clever things. I was at the time stuck in a loop though going “Well if im going to get such a device, ill get a PalmOS Treo” and then getting hung up on how to afford one with their very limited plan availability.
That longevity eminds me a bit of the HTC-Dream I had. Which I’ve thought about including. It was sort of the “beginning of the end” ushering in android. Yet something of a missing link too with it’s foldout keyboard and trackball. It lasted me a good long while and started my love affair with lineageos/cyanogenmod; which allowed me to eek out a few more years on it.
As I started saying this, I recalled how this was even true for many EARLY mp3 players!!
It’s odd in that syncing protocols made a kind of sense to me in the PalmOS days as it was kind of architecturally distinct. PalmOS didn’t have a traditional filesystem but was backed by a single universal storage database which contained both OS, apps and data. So some sort of translation had to occur between it’s database and the PC OS which had a stronger concept of individual files.
NewtonOS had a similar concept of objects and pools instead of files, but ill have to get around to the Apple Newton in a seperate post.
But having wierd ways of syncing files to our devices seem to outlast it’s usefullness and also I suspect for many would be MP3 players didn’t have the rationale of alternate filesystem metaphors.
