As the owner of two iPads, a Motorola Xoom and a Samsung Galaxy Tab, I know how useful mobile devices can be. One major drawback, however, is the difficulty of transferring files to and from these devices. Depending on the device, you may not have connections for external drives (as is the case with the iPad). While you can use cloud-based storage services such as Dropbox, you must have Internet access to order to make the transfer. In response to this need, devices have been coming to the market that allow you to wirelessly transfer files.
