HBOGo

That's all I really need. Surface is kinda heavy for in bed watching of News Room, Game of Thrones etc...

But that will require the phone to have an orientation lock. I think you didn't receive the memo saying "you are REQUIRED to sit/stand upright while holding your phone"/s

Honestly, it's hard to pick just one.

Banking apps (I know some banks exist, just not any of the ones I use), MLB At Bat, Nook, more video streaming apps as mentioned, and many others.

If I had to choose just a single one though, it would be Zipcar. Having an app for that service would make my life much easier. (I know that I can use the mobile site, but that can't use a GPS to find cars near me, and it can't be used to unlock the doors, etc.)
