I love these two new apps I've been using.
Dropbox - 2GB free secure file storage (using Amazon S3) syncs to anything you connect with it.

InstaPaper - a "Read Later" bookmarklet for your browser, that also syncs if you need to your ipod, to read or reference something you may not have had time for.

What are some of yours?
