AppleInsider's own checks, the site said, indicate the 4GB model is the focus of demand, giving weight to our belief that the 1,000-song capacity is the sweet spot for mainstream music player buyers. There may be more capacious devices out there, but the majority of consumers simply don't have music collections large enough to warrant the higher price tag.

Båda undersökningarna håller dock med om att den svarta modellen säljer bäst och alltså har störst risk att bli slutsåld.
