Perhaps its because I justified my 16gb purchase by insisting that I wouldn't use the iPad for music much (although I've sync'd 2-3gb) but it only occurred to me today that I should fire up the iPod App in the background while browsing. The speaker(s?) is surprisingly good, like a unibody MBP, and I'm a little pleased with myself but chagrined that it took me a month to try it. I'm sure part is that I'm in the first of 7weeks away from my desktop (on which I listen to music in the background constantly) so my iPad usage has soared (have MBP for actual work, whipped it out for 15 min today). I do feel (but have not yet measured) that the battery dies a bit faster, but the battery life is so great it's not a big concern.
