... and what was wrong with my example? I used a third-party calculator to verify the ballpark. Not practical then? I suppose if you're not an audio guy. I do recall someone using the Pandora for mixing or dj'ing. Not going to dig up the thread. And by the way, my reasoning is not fear-driven. I also don't think Pandora-lovers need a lecture on the importance of battery life, just the page-by-page reminder should suffice. EDIT: I'm feeling that this thread has devolved, given the lack of data I suppose that's the only way it could go. I will kindly step out.
