While iPod and MP3 player growth continues to be impressive, a new web poll survey indicates that some users want something more in their next device: an FM radio.

When asked about the most important new feature that they desire in their next personal MP3 player, 33% of respondents to a Jacobs Media poll said they want an FM tuner, which outpaced increased capacity, a larger screen, and video playback in importance. Apple owners are especially interested in being able to receive FM radio in their next iPods, with 43% making the choice.

Conducted in late February through early March and consisting of more than 25,000 respondents from over 69 rock-formatted stations from all over the U.S., the study concludes that "iPods are showing no signs of stopping," according to Fred Jacobs, president of Jacobs Media.

Since the company's first poll on the topic in 2005, year-to-year personal MP3 player penetration has steadily increased. From the '06 to '07 studies, ownership is up to 47% of the rock sample, a jump of 34%. Among alternative listeners, two-thirds (67%) now own an iPod-like device.

The study also asked those who don't own one of these devices if they intend to do so in 2007 and nearly half (45%) said they are very or somewhat likely to take the plunge.
