The fact I had to use iTunes to put music on my phone and the lack of access to the filesystem were extreme deal breakers for me. There is also the impossible hoops you had to jump through to change ownership of a phone. I gave my mother my old iPhone when I changed to Android and it was impossible to scrub my account from it, even with a factory reset.
The environment felt way too sterile for my liking. It treated me, a legitimate tech savvy user, like a malicious imbecile.
Alongside this comment was an equally damning comment: “if your past games are competing with your new games then your new games aren’t worth buying in the first place.”
