To view the webcast, though, users have to remember that Apple is pretty restrictive. Unlike other companies who are more open in their live video, Apple makes a strong statement with these streams: Don't even think about using Windows, WIndows Phone, Android, etc.
You can watch the video at the above link, but only if you have an Apple TV (second- or third-generation with software 5.0.2 or later), an iDevice (iPod touch, iPad, iPhone with Safari and iOS 4.2 or later), or a Mac with using Safari 4 or later on Mac OS X v10.6 or later.
Apple's keynote is expected to begin on or around 10:00 a.m. PDT. Its Worldwide Developers Conference (WWDC) sold out in under two minutes, this year.
