Google Drive is finally live and available to all.
As expected, you get 5GB free, and the web interface is grafted in place of the old(er) Google Docs. There's some slight changes to the way folders/labels used to work... as it now translates into file folders directly (which is actually simpler than it was, to be honest.)
You can use the web viewer to view 30 kinds of different file types, such as photoshop and illustrator files (that's handy!), and as expected, you can expand your available space up to 16TB (if you're willing to pay a monthly fee of $799.99!)
More affordable are the 25GB ($2.49/month) and 100GB ($4.99/month) options, which should suffice for most users.
The Windows and Mac app are already available, as is the Google Drive App for Android. iPhone and iPad users will have to wait a while longer.
