Messenger has all the components in place already I guess. VoiP has been easy for ages. All Skype brought to it was Kazaa’s P2P networking, and a neat user application.
Interesting too, this Creative / Apple iPod “Zen” patent story. I told you so I guess. The main innovation with iPod MP3’s was not the compact portable storage format, but the really neat UI. I’ve never yet owned one, but I’m always impressed with it when I see people using it. Good to see they patented the right thing.
