I have been using DropBox.com's service for a while now (https://www.dropbox.com/referrals/NTM5NjM0Nzc5) and have really come to rely on this service to keep things in sync with my Home and Work machines. What is DropBox? DropBox is an on-line storage repository that allows you to store any kind of file you want/need and sync with multiple machines (as well as accessing those files from anywhere with an Internet access and browser). You can get 2GB with a FREE account (which you can get more FREE space through referrals). You can even share files with other friends with DropBox or Publicly with people without DropBox. There is an app on the market (free) called DroidBox, and along with this app, this has become even more indispensable. I don't have things auto sync to my phone, but with this app, i can browse everything in my DropBox and download/upload files if I need them and can attach to mails and so forth. Check it out. I backup my pictures to my DropBox so I can view them on other machines easily.
