On first glance I wasn't entirely sure if it was an integration (into gmail, for example) or a standalone product.

As I scrolled down the page I started to think it was a standalone product, but then there seemed to be this chat-centric layout which just confused me (as I'm used to dropbox where most of the real-estate is occupied by the files and their meta data). And then my mind went back to "wait...why am I logging with a google account?... maybe it is just a plugin for Gchat or something...thus the unbranded chat-centric layout...

Then I kept scrolling and the next section clarified things. But then I left the page thinking "My team shares gigabyes of files, thousands of them...how could I possibly store all that stuff this way, with a chat log that goes on for miles?" So I lost interest.

Hope that helps.
