1G iPod shuffle On the Way Out?

The Street speculates that the 1GB iPod shuffle is to be replaced or removed from the Apple product line, based on growing evidence:

* A survey of Apple retail stores.

* Apple's online store, which still says "Currently Unavailable" for the 1GB iPod shuffle, as noted in mid-December.

* The unavailability of this iPod model at major retailers, including amazon.com.

This further supports previous rumors that Apple will introduce new iPod shuffles at Macworld San Francisco.
