The Clickfree Traveler is the once and future king of automatic backups. The Clickfree Traveler is easy to use and fits into your wallet. You had me at wallet-sized.
All you have to do to use the Clickfree Traveler is plug it into your computer. That's it--no software, no nothing. The Clickfree Traveler will automatically back up everything and anything that is important to you on your computer. Having an automatic backup that fits into your wallet and is idiot-proof is a genius idea. If I had anything worth backing up, I'd be all over this.
