I would ADORE it if it turned out to be the remote for Airport express, although somehow I doubt it, b/c where is the hardware? But, please, who cares about battery life when you've got a (non car) stereo on hand, b/c that guarentees you can just plug in for an hour and go for the day. But this would be a major step up on competitors, provide one of very few seriously usable features, and make apple's version of wi-fi sooooo much more appealing, they might be able to turn it into dominance of the biggest personal computer innovation and trend since the web browser. particularly if it can find AE devices, and so you can use your ipod to play on your friend's stereo, and he on yours, and in general use your music however you want. Then comes the wi-fi version of ipod your bmw, and seriously, dell et al could not fool people into getting another player b/c it's a bit cheaper.
