A few more reasons:
* Capacitive buttons. Better than hardware buttons. The back button is amazingly useful.
* Video calling to any phone except iPhone. Facetime only works with iPhone, iPad and Mac.
* Better maps app, better YouTube app.
* Background downloads while you do something else.
* Notifications icons in the status bar.
* Ability to jailbreak (called root) easily from day one. No need to wait months for the jailbreak to be released. Ability to downgrade firmware any time easily also.
* Ability to upload any type of file to dropbox, your NAS, etc.
* Download any type of file from internet and being able to use it, like a .rar or .zip and extract its files inside.
* Weather on lockscreen, news, voice commands, etc.
* New Google Now and Google voice search.
* Radio FM. IPhone can listen to web radio, but there are places where 3G is not available.
* Ability to install apps that would never be allowed on ios, such as a torrent downloader, emulators, etc.
* Offline voice dictation on several languages.
* Backups are way more faster to restore with nandroid backup. Works just like an iTunes backup, but takes only 12 minutes for me.
* My 48 GB version cost me 300€ less than what the 16GB iPhone 5 costs. 16GB plus 32GB micro SD. I just can't understand how a 16GB phone can cost 669€ unlocked and 599€ on contract with my voice and data plan.
Nice things, but the phone is too big!
