As a subscriber to additional storage with Google (20 GB, $5/year) I'm really happy to be reading this because it will allow me to fully use the space I've paid for. I believe it was the cheapest option when I subscribed and while I have crossed the free storage limit I have yet to fully use 20 GB.
I originally signed up for it because I was sporadically transferring a lot of high-res scans between a computer which my school owns and my own laptop, so a permanent dropbox-like folder would not have worked. Now I'll also be able to back up my music/photos dropbox-style with the same service. Smart move by Google for hitting both services, although it's kind of sad to see such a great startup being approached by the web's behemoth.
