With the OS taking up a huge chunk of that 16GB and basic functionality like messaging taking up another 700MB-1.5GB, and not even counting photos and videos than can almost take up infinite amounts of storage; little is left for actual music, movies, apps, and other content.
Tinder alone is basically a 1.5 GB app. If you want to watch a movie and it's another 1 GB. If you want a decent sized music selection you are down another 5-10 GB. With every damn poorly coded app being around 100 MB you quickly run into situations where people with 16 GB are having to make choices and are dissuaded from purchasing Apple music and video content, let alone purchasing apps and playing games. Apple is essentially cutting into various app developer revenues by introducing artificial limits.
I, as a 16 GB iPhone user, would not be able to download or keep various apps on my phone that would be available for use if I had to trade off with taking pictures of my life. So app developers are losing out on revenue because Apple is putting these artificial limits on things for utterly retarded reasons. Please, someone provided me a single rational and irrefutable argument for there even being a 16 GB version, let alone a 32 GB one. Do you want people to buy Apple content or not, Apple. Do you want app developers to make money or not, Apple. I suspect apple is going to screw around again until their retarded greed leads to innovation that results in them having to buy some shitty company for 3.5 BILLION dollars again ... Beats. It's far less obvious how that would happen, but the effect they are causing is still there, pent up, who knows how it will burst free.
Stop being assholes, Apple, let people have enough space so they can actually use your ecosystem's products services without having to make hard trade-offs. You greedy bastards.
