Camera help - buying a new one?

I want to buy a new camera since my old broke - it was a Nikon S 3000 I believe? Anyways - I don't have a clue on want camera to get, so I need help. I mainly use my camera for concerts. And I need a camera that has:

- Great/far zoom - I love close-ups.
- In close-ups, focuses on the face, not background.
- Good filming quality - nice sounds and visuals (not blurry, etc).
- Easy to use, not so complicated

My friend suggested a Powershot by Canon, but then she told me that when you zoom for a close-up, it focuses more on the background? So I'm not too sure.

Do you know a possible camera that fits all these?

You need to visit a camera store and hold a few in your hands. See how the S3000 compares to your friends Canon.
