It depends one's lifestyle. I have my own company and work from home for 20 years already. So the PCs with the big 4K screens are always around. When I go to my summer's office it is the same thing. So I read/watch videos from the PC. Yes there were few situations when I knew I'd sit in a car and wait for someone for quite a while. So I downloaded book on laptop and read it. I tried reading from a smartphone but my brain simply can not digest properly from this size of a screen. When I read I follow the line but I also glance at the whole page. Not sure why but this is how it works for me.
