alt Hacker NewsWhat do you consider to be a "normal size screen"? Since you mention trackpad I assume it's a laptop, so 13-15 inches? That was considered a normal size screen in the 90s, I don't think we should consider the compromise that laptops are to be the norm.
It all depends on your vision, doesn't it? 13 inches was a normal-size screen when we had five pieces of information on it at 640x480, but now that we have 4k screens jam packed with elements, it's no longer a good size.
I'm not sure saying something like "we used to send letters to each other a hundred years ago so we should be fine without mobiles" is such an ironclad argument.
