A report from ABI Research found 58 percent of iPod users thinking to buy a new MP3 players are "somewhat likely" or "extremely likely" to spend their money on a Microsoft Zune digital audio player.
Roughly the same percentage of non-iPod owners said they were likely to opt for a Zune when they bought a new MP3 player. (Read: Minority Report: The death of the iPod.)
So why the fluid nature of iPod buying? According to ABI Research analyst Steve Wilson, iPod users don't tend to have the same levels of devotion to their hardware as Mac users have for their Apple gear.
Wilson said Apple will need to come out with some hot products next year to prevent their competitors from catching up.
