Hi everyone, Any of you using an external wireless drive to expand your iPad/iPhone storage capacity? I was wondering how I would get around the fact that after installing all the apps I need on the iPad Air (16GB), I will be left with something like 4GB, which is not enough for my close to 9GB of music. And although it seems like it's easy to connect an external drive to the iPad using the Lightning to USB adapter, once that is connected there is no way to power the iPad in case the battery runs out. So, unless there is like a hub that allows one to connect a drive and power the iPad at the same time, the wireless drive seems to be a nice alternative. Anyone using one of those? Or if not, can you suggest a setup? Thanks a lot!
