Ok, I'll give you some that aren't subjective.
- all conversations in one view
- ability to switch between different modes like text, messenger (skype), facebook
- facebook messenger built into the interface
- go to a contact, see their latest facebook updates, linkedin updates, look at their photos etc. etc.
- a useable music app built in
- music store built in
- built in location search at the press of a button
- a built in web browser that isn't already hopelessly outdated at the time of release
- office integration built in
- cloud storage and back up built in (skydrive)
I could go on, those are just the things off the top of my head.
