You Tube, I Tune - Now We Rock Together.
Apple is undoubtedly a leading innovator in the industry (if you wonder which one -- both), and so is Google; so expectations from the announced integration of AppleTV and YouTube are very high. Whatever may your (or my) feelings be about YouTube, it is certainly a defining phenomena in Web 2.0, and bringing YouTube to the living rooms of the millions of households is no small deal.
On a more obscure front, Apple also announced iTunes Plus - new DRM-free, higher quality audio format offered through the iTunes store. Unfortunately, so far, the selection of music in iTunes Plus is rather limited. Considering the level of paranoia in the recording industry, whether iTunes Plus can take off remains an open question.
