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).
