MacOSX.com claims to have received information about a product called the Apple iBox.
According to the site, the iBox is essentially a modern set top box which would act as a wireless media hub connected to your television. Reportedly, the appliance will offer versions of iPhoto and iTunes to help manage your digitial media.
Readers should note that anonymous emails to random websites, however, tend not to be very accurate. Apple Set Top Box rumors have been around for years... and even made our Reject List for 2003.
Apple actually did produce an Apple Branded Set Top Box (photo) in 1995, but the system never went into full production. Early versions/prototypes can still be found floating around.
