Another option for storing (and sharing) files online, for free (basically – read on for details). Google & Gmail users: Google Docs has made “Upload any file” available. When signed in, click on “My Account,” then select “Docs.” You’ll see an introductory message like this:
Using the service is intuitive and easy. You’ll have the option of uploading files in their original formats, or converting to Google Docs formats. You can store files up to 250MB in size for free, and are allotted 1GB of free storage space. You can upload any file types you wish – MS Word, PowerPoint, Excel; flv files; music files – whatever you wish. If you require more than a GB of space, it’s available for a fee. Costs are $5 per year per 20GB of space.

If you need to work on a work-related file at home, instead of saving it on a thumb drive, just save it to Docs and access it via your Google account when you get home.
EDIT: BTW, you can view files on your iPhone or 3rd gen iPod Touch, and of course can email them. I have found that I can edit Excel files on my iPod Touch, but cannot modify Word docs. I also can view pdf files on the Touch.
