It's always exciting when Apple posts live streaming links and allow the underprivileged fans to watch the press event live! Starting today at 1300 EDT / 1000 PDT, you can watch it on your Apple TV, iDevice or via any other means of web streaming.
Live Streaming video requires Safari 4 or later on OS X v10.6 or later; Safari on iOS 4.2 or later. Streaming via Apple TV requires second- or third-generation Apple TV with software 5.0.2 or later.
If you can't stream the video live, then you can always tune in to my two favorite live streams via The Verge or gdgt. I'll probably be tweeting my excite too. I've been waiting to pull the trigger on a MacBook Pro 15" Retina Display for over a year waiting for Haswell. Maybe I'll wait for Broadwell?
