For years I have been looking for portable, battery-powered external hard drive. I do a lot of consulting and always keep backups of my work, so I keep a portable external hard drive with me. I also have an extensive music library that I want to have readily available to access from my laptop and portable devices, but I hate constantly moving music files to my “iDevices” just to keep the selection fresh, and all too often, I’ll want to hear some songs in my collection that I didn’t think to move.

Wait, I could do all of that on iCloud (or any other cloud service), right? Sure, if I want to wait for files to upload / download, and I want to pay for all the bandwidth to move the data – I’m usually on the road or at a client site when I want to move data and I don’t jailbreak my devices anymore – it’s just too much of a hassle for limited benefit and extra instability.
