Makes for a good read, but somehow I have to doubt that Apple or Sony would want this product to come out. Each company makes their own music players and music software… they both have their own music stores as well. Looks to me to be a pipe dream, or a free time hack from a developper over at Apple.
Although, the thought of buying my music from the iTunes store wirelessly has me drooling!
Update: As expected, this was just a hoax. Still would of been cool if it was true :)
