Like one or two years ago, I got myself a free Dropbox account. I use it occasionally to exchange files with some friends. It does an excellent job at that. Basically, it works like any network folder. Except it is not within a local network, but over the internet.

Dropbox serves me as an occasional replacement for both email and USB pen drive. Instead of sending a modified file by email or bringing around a dozen of photos on a USB stick, I just put them into the shared folder. This also very useful for files such as flyers, templates. They may easily grow to big to be sensibly sent by email.

For all my use, a regular free Dropbox account is more than enough. As in, I have less than 1 GB in use, and I could easily free some of that space. You start at 2 GB, and can currently get up to 10 GB free (+250 MB for each referrer; if you use the link above you’ll already start at 2.25 GB). But for my use, this is already a lot.

Note that there are a couple of alternatives around. For Linux (only) there is Ubuntu One, and there is Zumo Drive and Box.net just to name a few. I havn’t tried them, given that Dropbox works for me well enough.
