You just perfectly described the computing world before 1965 & IBM’s 360.
A range with 10x - 20x (? recall failure) of compatible models.
This was repeated with microprocessors
- at each ‘process step’, one clock frequency option for many years.
Can’t recall who invented the range of CPU options we now have:
server, desktop, laptop, tablet and ‘embedded’
Might’ve been two variants of 486, can’t recall.
There was a tower of babel with Networking for decades,
first the physical layer,
then the packet layer,
then network / protocol layer.
We ended up with cat-5/6 twisted pair as the most common
physical layer (with RJ-45’),
async packets framed with Ethernet,
running IP protocols over the network layer.
“Internetwork” is a give away in the name “I.P.”.
This, despite IBM & Microsoft’s (& others) considerable efforts otherwise.
Mature markets require “Standard” parts / services,
so consumers can mix-n-match as they wish.
Standards facilitate “substitutes” & competition necessary
to generate low-margin, high-volume commodity markets.
By definition, commodity markets trade “fungible goods”
destined for consumers. So many of these, hard to list.
Standards - where manufacturers agree on common designs -
only appear when manufacturers agree they’ve a common
interest in building “volume”, not locking customers in.
This happened very early with bipolar TTL logic.
Smart phones are mostly Linux / Android,
with Apple still able to sell non-commodity designs
at premium prices.
Remember Microsoft’s foray, via Nokia, into Mobiles?
“Pocket PC” and “Windows Mobile” / Windows Phone:
Crashed and burned.
Even Nokia, then largest phone seller,
with the proven Symbian O/S,
failed against Android.
