To me, Jobs did us a favor. I use my phone, nice laptop, a mix of Apple, Android, Linux, Windows to do amazing things, talk with people around the world, etc...
Total win.
Stuff we take for granted today... science fiction made real. No joke.
What I think should have happened is Woz continued with the Apple 2 line. Jobs didn't need to kill it to get his vision out there.
I got a GS to to tinker with, but haven't hooked it up yet. Too much going on. But, it hints at what would have come.
Today, people are always doing what Woz did. It's fun to build or run a little micro. One can get right to the bits, control things.
It may well be that Apple could have continued right along, a parallel to the PC, and had that happened, we may well have seen the product of that being the reference, or standard hack / hobby platform.
Now, we do have the Raspi. It's not bad, but it's also not easy to make effective use of it low level.
Something with roughly that amount of compute power, but accessible in that open Woz way, would be just perfect.
Today, I think equivalent magazines are Make, Adafruit's blog, internet & all the resources available online. So, I think such magazines / content still exist & they still have an audience (if not a larger audience, thanks to MOOCs & Arduino / Pi, etc.)
If you are making an argument that, in general, most magazines today publish trash, and somehow, the magazines published in the past were more content rich.. I'd challenge that with two points:
a) Content heavy magazines / websites still exist --> Economist, Ars Technica, etc. They have a strong audience.
b) The pool of people reading has gotten larger; and more magazines are catering to a more diverse population, some of which, as you imply, are drivel.
But to say that such content is no longer published, or is accessible, I would think, is incorrect. I'd argue such content is much easier to access today than ever before.
