ahh but you don't live in Canada, $50+ a month of 75gb of bandwidth, its much cheaper to store steam backups on drive, especially if your friend already has a local backup, then to download again.
Additionally moving from university, internet came with residence, to moving back home, I find myself reverting back to using usb, before I used to stream all my music/video via youtube and other networks, now I download, used dropbox a lot of files, but the now I've gone back to usb. It's like travelling back in time...
