What is radio, anyway?

This article on CNet.com is enough to make the average radio guy's stomach churn. When you think about it, though, picking up a radio and turning it on is a little easier than 1) signing up for a download, 2) downloading, 3) transferring program to IPod, 4) remembering to listen to program. Radio has such a natural advantage over the computer kluge...too bad it's programmed for its sales departments and Wall Street, rather than listeners.
