I've never heard someone use Apple trademarks as generic terms. The generic term people use for a touchscreen smartphone is...a smartphone. Likewise, a generic term for a tablet is "tablet". I've never heard someone use "iPhone" to refer to all smartphones or "iPad" to refer to all tablets.
Though as a kid, I know my parents would say to "put away the Nintendo" when it was the PlayStation stuff that was all spread out on the floor.
How about the IBM PC? Plenty of home computers existed prior to the PC, but today 8086 code dominates at all levels of computing.
How about Google's search, or Google Maps? AltaVista and MapQuest came first.
You mention Nintendo and PlayStation, but Atari was before both of those!
How about Facebook instead of MySpace?
The point is that saying that the person who comes along and copies you will do it worse because they don't understand it is often wrong.
I think "pop" is a hold over from the older English fizzy pop
Here in the UK people just have "Smartphones" and "tablets" (tho I do hear people calling generic tablets "iPad" sometimes).
The USA, love it or hate it, is the most dominant marketing force on planet earth.
Edit: How about Google? They copied Yahoo and AltaVista, and their search engine has become so ubiquitous with searching that it's a word in the dictionary now.

Some of the category names don't even match up - adhesive tape is definitely not what comes to mind for Durex for me.
Consider: thermos, escalator, linoleum, trampoline, zipper, scotch (as in tape), jeep, xerox, jacuzzi, dictaphone...
I think branding to generic really depends on linguistics of target market, brand writers and brand saturation in target market.
A brand name that is hard to pronounce is less likely to be used and how often do you think about the Slovakian pronunciation of your brand?
The US being a large linguistically similar market would be more susceptible to this.
Are you from the US? Because here in .eu "iThing" is definitely not the generic term for pretty much anything.
“Apple Pay” being used as a generic for “phone-based contactless payment system”, “iPad” as generic for “tablet”, and “iPhone” as generic for “smartphone”.
Beyond that, though, your other examples just seem weird, because I don't ever hear anyone use iPad or iPhone as a generic term. "I have an Android iPhone." "Hey, that's a cool Microsoft iPad." Nope. And the Mac was the first computer anyone outside of nerdspace ever heard of using a GUI and mouse, and I'm sure that's led to some pop culture confusion, but that doesn't strike me as comparable to the other examples anyway. "GUI" and "mouse" are generic terms.
It was generic enough to form part of the word "podcast", which has stuck around.
i've never heard anyone use iphone as a generic term. phone, mobile, cell, cellphone. these are the only terms i've heard.
and while i'm add it, mp3 player is what i've heard EVEN it is in reference to an ipod.
ipad? nah, generally i've heard tablet.
and finally, i've heard no one say retina, i have heard HD, HiDPI or 4k (even if it's not).
Apple wasn't the first company to make an MP3 player, but the generic term is basically 'iPod'.
Apple wasn't the first company to make a smartphones or touchscreens, but the generic term for a touchscreen smartphone is basically 'iPhone'.
Apple wasn't the first company to make a tablet, but the generic term is basically 'iPad'.
Apple didn't invent high resolution displays for personal devices, but the generic term is basically 'Retina display'.
We can go back in time, too. Apple didn't invent the mouse or a GUI, but lots of people pointed to the Macintosh as inventing them.
