How can you have FUD about the best selling product? WTF...
Since when are sales figures an insulation from FUD?
You can if you are trying to instill Fear and Uncertainty and Doubt about the best selling object so you can sell the poorly selling Zune.
Regurgitating old stories of problems with the iPod, including some quotations that are verbatim from two and three year old articles about issues that have long since been fixed (Batteries, etc.) as though it is current is, I submit, FUD.
