I currently have an Airport Extreme, and I save my necessities like iTunes music purchases and some documents on a 2GB USB flash drive. My iTunes music library is getting bigger, and I'm creating more documents that should be backed up. I DO NOT want an external hard drive. I tried one of those, it vibrated too much and the software stunk, so I returned it. For me, it's between a bigger USB flash drive that can definitely store all the essentials (a 32GB one would hold me for years) or Time Capsule. Time Capsule is tempting because it does everything automatically using Time Machine, and it's built in to the router (I like having something that's NOT attached to the computer that works with Time Machine)... A bigger USB drive is also tempting though since I already have the Airport Extreme and I could use the USB drive to store my essentials. Also, just a question: whenever I add a song to my iTunes library and want to back it up with the USB drive, I always delete the entire iTunes library (the library that's located within the Finder under Music) and drag and drop the whole thing again onto the USB drive. This takes a while, so is there any way to just drag and drop the extra music files to the existing iTunes file on the USB drive?
