Does anyone know if the InvisibleShield for the 60 GB iPod will fit on the 80 GB iPod? Are the new 80 GB iPods any larger in size that the 60 GB? I know on the InvisibleShield website they have 60 GB and 80 GB iPod InvisibleShields. I didn't know if there was a difference. I wanted to go ahead and buy an 80 GB iPod, but my local CompUSA says it only has the 60 GB InvisibleShields.
