I don't get why you lump iOS and Android together when they make so different trade offs in terms of quality, polish and security vs. functionality and freedom.

I don't get why you lump iOS and Android together when they make so different trade offs in terms of quality, polish and security vs. functionality and freedom. Bluetooth is a good example... You can use regular (even Apple's) wireless keyboard on an Android phone out of the box. Even wireless mice, it's a fun thing to try, and see a mouse cursor appearing on the phone screen. I also like that I can plug a USB SDR device on my phone and explore the RF spectrum with an open source app. Something I would not dream to do on iOS, which can't event handle a USB thumb drive. So I think the situation is very different between the two ecosystems, and it's great that people can choose according to what they value the most. Of course we want the best of both worlds and the two platforms are converging a bit along these lines but a device that allows any app to be installed will probably never be as secure as one that only takes from a curated list.
