Besides that, have you thought that everyone’s lifestyle may not be just like yours?

Are we really going to do the whole Slashdot meme “Do people still watch TV? I haven’t owned a TV in 10 years”.
Now I am more settled and have a family, I watch things on my phone a lot less.
Rather than using a tablet, I was using a Kindle Paperwhite so that I can take my library with me. I don't use it to browse the web.
I have quite a bit I use my SE, including Evernotes, my meditation timer, my Go client, etc. I don't actually need a tablet.
I have a tablet now. More because my wife and the T-mobile guy convinced me that I can use it as a backup 2FA device with Krypton. There are some use-cases that I am looking to incorporate things with... but again, I don't actually need it. I probably won't take it with me when I travel.
But it's more about do enough people want to watch video in public or on the go such that large phones became the dominating choice?
Given your handle I can understand your concern...
... Why?
I don't get it myself, but for whatever reason a lot of people do enjoy this. I'm guessing as a coping mechanism. Probably in the same vein as reading books/news, or playing video games etc.
I have an old friend who every night picks out some criterion collection DVD to watch, and posts about it on social media before/during/after.
That said, I have a tablet I use for long-form reading/youtube (90%+ reading) during train/ferry rides > 10 min, but obviously haven't had to use it much recently. Mostly reading.
