I don't use my phone as a pc, I use it to run a few generic apps, make notes and reminders and, obviously, as a phone.

iPhone does the trick for me in that regard, the app library is huge, the consistent design is great, the way it syncs with my macbook is irreplaceable.

Being blocked from running arbitrary code on a phone is not a big deal to the vast majority of users. If that's a dealbreak, buy an android phone. But lets not pretend that doesn't come with huge tradeoffs if you like what the iPhone provides.
