Most Requested Windows Phone 7 Apps

I only catch myself REALLLLY missing Pandora, a decent G+, and the Facebook Timeline update.... so there's my top 3.

Oh, Word With Friends...but that's serisously all I can think of, so I thought I'd ask for help?

What are some specific apps, or types of apps, that you guys have noticed are missing from the marketplace?

What would you really like to see show up? Maybe we could start an actual running list here, and somebody will notice :)
