I finally got around to signing up for Carbonite, and am amazed at how well this backup service works and how easy it is. In my mind, everyone who uses a computer should use Carbonite. The service costs $59 a year for unlimited storage. You install it, and it automatically backs up the files and settings on your desktop computer. Then if you like, you can use their Carbonite Access iPhone or iPad app to access your files anywhere, anytime. The iPad app was just released in March.
