The upgraded Public Radio Player iPhone app gets a rave review on the ars technology blog.  The improved tool offers public radio fans more and easier access to on-demand programming.  Interesting conclusion to the post:

“With commercial radio relying so heavily on ads and Arbitron ratings, an iPhone app that gives listeners this much control over how they interact with the content is going to be a tough sell to broadcasters. But as consumers become increasingly accustomed to an on-demand world, radio is going to have to figure out a way to change with the times.”

On a sorta related topic: Why don’t we have radio TiVo?  All I’m asking is the ability to run back maybe 30 or 60 minutes so I can hear the rest of that great segment that was still going on when I arrived at the office.  How hard could that be?
