Putting aside the convenience of having the ability to access the internet at a moment’s notice anywhere you are (something that ranges uneccesary but nice to almost essential, depending on the situation), flip phones are a pain in the ass when it comes to texting, which is how the majority of people communicate these days. Durability means little, because I have a case, my iPhone is actually less scratched/chipped than any of my previous devices (as in, it has no scratches at all).
For my phone I use Safari. Never had any reason to use otherwise. I also use Safari for my laptop, though there have been a few instances where I’ve noticed Chrome would be better (my bookmarks are on Safari though so I haven’t been eager to switch).
