There's also email FTP and web transfers but given your post I can't tell why or what's at issue here. We also have iTunes on Apple or PCs. And there are iTunes Alternatives (see google)
Without the help of Google docs or dropbox or any other cloud storage service it seems impossible to transfer any file at all, I'm wondering if there's any way to hack that?
If not then I'm probably gonna have to switch to android tablets(which I wonder if is even better on this regard)
