Two readers have sent in great spoofs of the Zune ad campaign:
Deepsignal's Welcome to the Orgy ("Share music=get laid/but then the next morning the music you share is gone, just like a one night stand/DRM, it's like that empty feeling/it's ok. you weren't compatible anyway")
Appleeqlove's Welcome to the Social (bong hits and Zunes)
(Thanks, Ingo and Ivan!)
