Dropbox is the solution. Dropbox is free for the first 2GB of storage. Dropbox sits on your computer like a virtual folder, always in sync with with where the files are actually stored on the internet. Drop a file into your Dropbox folder at work and it is instantly available to any other place in the world the moment you log in to your Dropbox account. And for all your computers, you can keep a Dropbox folder sitting right on the desktop of each machine so your files are always available.
And another benefit of Dropbox is that you can share any or all of your Dropbox files with others, so it is a great way to share resources or collaborate on a document.
