Useful. The cloud has just gotten a tiny bit more convenient. I was a skeptic. Now I use Google Docs almost daily. In my opinion there is no more doubt that Google is right and that in 10 years there will be no more applications that we install on our hard-drives or apps that we install on our phones. The OS will be a browser.

What I'd really like though is the ability to attach a file in my Google Docs a/c to an email I am composing in Gmail

Is this the beginning of integrating all personal info stored in various Google products under one search box?

Sounds kind of nice. Though a functional email search would be my preference...
