I'm looking for an external hard drive, compact, that I can connect to my iPad 2. I'd like a product that uses easily found cords (!) that is small enough for a shoulder bag, tote, or drawer. I'd also appreciate recommendations for backup software. Lastly, if possible, I'd like to connect (what cords?) my iPad 2 to my Windows (sorry, dirty word) netbook and backup to an external hard drive. Can I cross-communicate/cross-pollinate?
