Hi Jim,
For the record, I did not use the term ‘fundamentally’, and I agree that this has been an iterative process
My background is in engineering. That is 45 years of embedded processing with a specific focus processing technologies including SoC design and use. This is going back 45+ years.
Major improvements that phone technology has brought by technology include:
Chemistry: Battery tech
Software: Signal processing, Power managememnt
Hardware: SoC design, low power design
Mechanical: Optics, Packaging
In all of these areas the Cell phone has absolutely driven the technology edge. I would agree that this has been iterative, but the sharing of this tech is in exactly the other direction that you suggest. The above mentioned improvements have found their way into other commercial arenas.
The standard home computer has been slow to accept SoC technology, the exception here is the spate of products such as the Raspberry Pi, etc.
I am happy to carry this conversation on, but it should probably be off line as I don’[t want annoy / bore others.
