The Apple TV set is being held back by content and licensing deals, claims Sterne Agee's Shaw Wu. The analyst cites "checks with industry and supply chain sources," who also allegedly learned that Steve Jobs was "very excited" about the opportunity presented by a TV, which the company could differentiate from the competition through user experience. Wu notes though that while iTunes currently has plenty of content, it's intended mainly for downloading, and Apple has dropped TV shows from rental options.
