What's up with the iPod?

A recent ChangeWave survey shows an unprecedented slowing of iPod sales - with only 2% of consumers saying they'll buy one in the next 90 days.

That's 3-pts worse than at the same time last year, and 6-pts worse than two years ago.

These numbers are in stark contrast to comments by Apple Chief Operating Officer Tim Cook at a recent Goldman Sachs technology conference, where he stated that iPod sales weren't slowing down.

But at the same conference Cook also admitted that he would "...rather have Apple cannibalize Apple than have somebody else cannibalize Apple."

This tacit admission - coupled with our recent ChangeWave survey showing the lowest level of iPod sales ever - says that the rising popularity of the iPhone signals at least some trouble ahead for the iPod. Keep your eyes on Apple's next earnings announcement.
