Rejected Limited Edition iPods
(hat tip method shop)

Some of my favorites:

Ashlee Simpson iPod:
Special vocal equalizer plays a random voice track each and every song. Also comes with free SNL tickets and a $50 gift certificate for "acid reflux" medicine.

The jloPod:
Extra large rear battery attachment.

The iMSFT:
Preloaded with viruses, sloppy code, and vaporware. Includes a special BSOD function.
