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.
iPhone 4, 4S, 5, iPod Touch 4th and 5th gen, iPad 2, iPad 3rd gen, and any mac with a front facing camera running Lion or snow leopard with the FaceTime app. That's a pretty long list.
* Better maps app, better YouTube app.
* Background downloads while you do something else.
Does this on iOS 6 too.
* 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.
Subjective, not everyone feels the need to root or jailbreak. This is not a feature..
* 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.
No need to mention the huge security risks with this ability...
* Weather on lockscreen, news, voice commands, etc.
Siri works on the lock screen, and she'll give me weather or any other typical siri function.
* 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.
Again with the security risks involved.
* 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.
Backup time depends completely on the content being backed up. Also, with iCloud backups iOS devices can backup automatically while you sleep. I don't tend to count time while I sleep..
* 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!
