Apple rolls out iTunes 10, new iPod Nano, and Apple TV
4. New social network, Ping
Ping is today's most unexpected Apple announcement. The social network will come baked into iTunes 10 and allow users to connect with friends and musicians. Apple describes the service as a music discovery program. "Follow" people to discover what they're listening to, watch their favorite music videos, find custom top-ten lists, suggest songs to others, and learn when musicians will tour in your area. Ping is free, but Apple hopes all this sharing will lead to a bunch of new 99-cent sales.
