There is a lot of talk about cloud computing, and accessing files that would normally be stored on a desktop or laptop with a mobile device. If you don’t have a Pogoplug, may I suggest Air Sharing.

Air Sharing is an app that allows you the user to mount an iPhone or iPod Touch as a Wi-Fi drive on your computer (Windows, Mac, or Linux) or connect from your computer’s web browser. You can then drag and drop files between and iPhone, or iPod touch and your computer. It also allows for viewing email documents in many common formats and sending email attachments.

You should be able to get it for the iDevice platform for $2.99.
