Some even watch movies on their phones. Squinting a phone that long would give me a headache!
I said the same thing, right up until I found myself without an option for other entertainment and watched a movie on my phone for the first time. Yeah, the screen is smaller than a laptop or TV (obviously), but the picture quality is excellent and there was absolutely no squinting involved, even without wearing my glasses. It depends on the quality of your phone’s screen and its size, of course, but today’s average smartphone has a perfectly fine screen for watching movies.
I tend to watch movies when I find myself unable to sleep, and picking my phone up off the nightstand without having to get out of bed or fire up my laptop is a godsend. Only problem I have now is I used to have unlimited data and now I’m restricted to 6GB/month, so I have to remember to switch over to wi-fi to stream anything.
