Alleged Screenshot Of Google Drive Surfaces

Does anyone know (or have any educated guesses) if Google Drive will have an installed state like DropBox, or will it be entirely web-based?

It's funny, but I didn't think I'd like the fact that I had to install DropBox. Now, I can't imagine any other way it could work. Then again, I'm not paid to solve these problems.

So someone has learnt how to use Developer Tools on the Google Docs page?
