Official description of Google's GDrive

As mentioned here and here before, it seems like Google is working on some kind of online storage service, called GDrive. And googlesystem.blogspot.com has another hint, found inside a file used by Google Pack - take a look:
So the product category is "online file backup and storage" and the description of the application is:

"GDrive provides reliable storage for all of your files, including photos, music and documents. GDrive allows you to access your files from anywhere, anytime, and from any device - be it from your desktop, web browser or cellular phone."
