Today it looks like iOS 4.2, the new version of Apples operating system for the iPhone and the iPad, is being pushed back another week. I've been trying out AirPlay on my iPad (the developer preview) and I have to say this is the future. In http://www.apple.com/itunes/airplay/iOS has a killer app beyond anything else in the mobile space today. I'm not kidding.
AirPlay let's you stream music and videos to and from any iOS enabled devices. Whole there aren't many such devices yet this is the future of media we've been waiting for.
Coming home, sitting down with my iPad and than choosing what I want to listen to on my wifi stereo system is a form of media disintermediation that really takes the leap from 50s hifi systems to the visions of the future represented in movies such as Total Recall or Minority Report.
AirPlay really does change everything. Lets just hope Apple opened it up to third parties. This is the way we'll want to consume media in the coming years. Let's hope it get wide adoption on all platforms.
