Well I too had the first iPhone just a few weeks after launch and the 4 before switch to various androids and now back to iPhone.

Watching content back then wasn’t as widespread as today so in that sense it’s quite useless imo. Watching a 1080/4k on YouTube or watching a show on Netflix/Apple TV+ on such a small form factor seems like an annoyance.

Besides, my phone is what I use for 95% of my computing needs. Banking, identification.
