MacBook Air vs MacBook Pro

Hey everyone. So I'm getting a new laptop soon and I definitely want a Macbook but I'm not sure which one I should by. I like the Air's portability but do you think the Pro is better laptop overall? Here is what I would be using my laptop for:

-Surfing the web. (Often have a few tabs open at once)

-Lots of writing/typing

-Downloading songs from itunes, I do not have many songs right now. (And a few apps)

-I'll probably be doing multiple things at once so it can't lag

-Video Streaming

Any advice? I'm going to wait until after WWDC to purchase but I just wanted to get another opinion. Thanks.
