Wouldn't it be cool if someone could make a time machine app? You would plugin your iPod to your computer, start the app, and it will make a total backup of your iPod. So if you ever screw something up bad, you just plugin your iPod again and open the app again and flick through your recent backups. Not only would this be the ultimate compliment to other mac apps like MobileFinder, MobileStacks, and Dualcorex's Leopard theme, but it would also be extremely useful! As long as you make regular backups, you'll never have to restore to factory again if something goes wrong. Just restore to the backup you made the day before you screwed something up.
