Number 1 is the only feature I envy.
Number 2...I don't know, alot of the photo apps have those additional features. And even then, as you said, outside of exposure and focus controls, which are both available on the iPhone, I dont know if I'd use those settings. Plus, most of the photo apps I use are iOS exclusive.. (VSCOcam, for example)
Out of curiosity, how different is your usage? Am I using my phone differently that I don't find the benefits of Android to outweigh the iPhone?
You could Google Music in combination with iTunes as well.
And answering your question.
1. I like flashing custom ROM's to add new features/ tweak exiting ones too be better.
2. I find widgets useful.
3. I love Google Music and the fact it's free.
4. I like i can Root and remove any apps i don't want on the phone.
5. Can't stand the iOS keyboard.
6. Can change the default apps for things.
7. Alot easyier to share information between apps.
8. No reliance on a piece of software like iTunes.
9. I like how i can make my phone how i want it to look like instead of what Apple wants it too look like.
10. Don't like how in iOS if there is a bug in say the mail app for example a updated version can't be pushed to the phone via the app store like in Android i would have to wait until the next incremental iOS update. To me that seems very backwards.
11. Can dump any old video file on my Android device and it will play with a 3rd party player, with an iOS device i'd have to re-encode the video unless the file happened to a in a format that Apple likes, which is time consuming and tedious.
Thats the plus's for me off the top of my head according to my usage.
