Ah yeah, you seemed like you had some knowledge and interest about it. I agree it does seem like the early cell phone era may disappear in a way that retrocomputing won't revive.
This discussion did lead to me to find a particular touchscreen test video by Moto Development Group <https://www.youtube.com/watch?v=JR1sJhtgkK4> -- their blog disappeared when they were acquired, but apparently their youtube channel [1] wasn't deleted. I used to link to that blog post to point out how bad the touchscreen drivers were in certain phones.
Anyway, if you have more questions feel free to send to tp at tompark.com and I can try to connect you with someone who knows the answer.
