You just might be. 😉
Actually I'm sure there are lots of people who want this. I'm not one of them and will never understand why someone would buy a 20-40 GB "MP3 player" and listen to the radio on it. Just put the iPod on shuffle. It'll be all of your songs (so I assume they are all ones that you like) and no commercials.
Well, there are several radio programs that I like to listen to, none of which are available off-air, while I'm at home. But I'm also a frequent traveller; and while the iPod already works great for storing/listening to all the music I own, and doubles as a portable hard drive for storing digital photos and random other documents, there are some things that you need a radio for, such as listening to news reports, talk shows, weather reports, local programming (which is often not in English and otherwise inaccessible), and so on. Besides, listening to the radio for a bit, especially in other countries, can add some randomness and variety to the music you're listening to, rather than listening to the same music you own over and over again (especially good if you don't buy massive amounts of music and don't own thousands of songs).
Individual radios are cheap and can be small, true. But it would be much more convenient if I didn't have to carry around an extra device just for the radio. Especially since it would be a very small and uncostly addition for Apple to throw in. (doesn't the iRiver or whatever it's called already have a built-in tuner? I don't want to buy that, though, because I need the portable hard drive functionality, too). Additionally, having the tuner built-in would let you be able to record radio shows or music off of a station into mp3 right on your iPod (assuming they let you do that in the software, which they should).
An added bonus of the built-in tuner would be that, together with one of the transmitters, you could share music wirelessly on-the-fly with other iPods. Like that jack-sharing fad, only wireless. Depends on how powerful those transmitters are, I guess.
I also agree with the line-in request for recording purposes. If you're travelling, and don't have a computer, the line-in would let you be able to encode music from new CD's you buy, or even cassettes, direct from any player with an appropriate line-out cable.
