Dear Aunt TUAW, In the "Post-PC" era, is there a way to get an audio file, such as one stored on Dropbox, onto an iPad? Is a tethered transfer of audio from iTunes the only solution? Your loving nephew, Chris R. Dear Chris, In a word, no. iTunes maintains its own asset library system that isn't generally accessible (except for reading) to developers. Third-party apps can browse the unit's iTunes music library and choose tracks and play them back (and, even access the data directly if they need to). But there's no way for them to modify the library itse
