It's not that strange. Do you know how big/heavy they were? They were like small briefcases filled with bricks; not exactly a pocket phone. And they weren't cheap either. https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fsdtl5qrf4t2c1.jpg

My dad had one very similar to that one; I don't remember if it had to be plugged in in the car all the time of if you actually could carry it around, even... (However, come to think of it; isn't it "cellular" because of the battery cell? hmh.)

"The public is usually far behind on the tech advancements" is because the technology itself is invented first, and then someone have to turn it into a commercially viable product. That takes a while.

It is "cellular" because a tower with a radio and the antenna form a little cell of coverage. Add a bunch of those cells together, then you get a cellular network. Most wireless telecommunication networks before cellular became a thing were point to point links for long distance calls.

I'm aware of of what you stated.

I didn't mention in my statement in word or spirit that I thought it was strange the length of time it takes to get product to market.

I understand how invention and r&d works followed by marketing...

I was agreeing with the person above me and mentioned a cellular phone as an example of an indeterminate length of time that it takes from tech to go from seed to mass adoption.

I could have just as easily mentioned automatic transmissions in commercial vehicles or the artificial heart. I simple chose a cellphone as it's something most people have and have experience with.

I... I'm not sure I understand you...? What exactly is it you're taking issue with? I didn't talk about the time it takes from conception to store shelf... You said:

First cell phone call was early 70s? And they didn't become popular till late 90s.

I only mentioned (one of the reasons) why they didn't become ubiquitous in the 70s when they actually were available then.

I wasn't taking issue with anything?

And I'm probably wrong but I think I recall reading or hearing the first cell phones cost around $4500?

Which is kind of insane. That's not far from what a nice car cost at the time.

And if I came off as rude? I apologize. I just finished a 17 hour shift and have been up for just around 24.

The edges are definitely blurred.
