In the past people used custom-made javascript code and third-party tracking systems to check:

• what page has adsense clicked,
• how many clicks,
• what keyword get more click,
• characteristics of clickers,
• etc.

Now they can do all those just by Analytics itself... no more javascripts, no more third-party sites. I'm personally very happy with this new feature, becaues I've been waiting for it since I started using Analytics nearly 2 years ago.
