I have found this adapter to be very useful. All though it is considered to be a camera connector kit adapter, with the app "fileapp" it can be used to have flash drives and external harddrives for file access. With iworks you can save a file to the ipad and then transfer it to the flashdrive or ext hdd by using the "fileapp" app. Awesome, eh?
