I sort of discovered this accidentally twice.
First was when I go the Kindle I realized I could make the text as big as I wanted so I would do that, as stated before.
Another time is when I wanted an external monitor and I bought a big TV because it was much cheaper. Because the TV was bigger the text was also bigger, and I realized how much easier it was for me to work.
I think I used to feel like there was a "coolness" factor to keeping the text small. I don't know why I thought that, but I think what's much cooler than having lots of small text is actually being able to read and understand the text on the screen.
Now I have no desire to impress anyone, and I keep my text in the browser at like 200%.
For me it's not coolness it's just context, 16:9 is too short to fit enough lines and scrolling and jumping is as annoying as tabbing in and out.
This is also one problem with ereaders for me, especially for anything technical. With paper when the textbook says refer to fig 13.2 or we covered this in section 4.3 I can just flip to that page with my fingers as a bookmark, read it, and go right back. Just not as tactile on computers. Even if you did like lsp assisted jumping all over the place you quickly forget what the heck was going on and where you came in from.
Of course maybe someone will come and correct me but this is just what I experience. It's still better flipping pages for technical stuff. It's like scribbling a DJ disc, imagine doing that with a mouse or keyboard. It's just… different.
