Apple announced iTV today, a set-top box that will wirelessly stream audio and video content from another computer. Expect the device in 2007. Mark Cuban has a good take on the announcement.

Of course, geeks and homebrew enthusiasts have been doing this for quite some time now with the MythTV project. The Myth developer team just released another version recently. The interface and program guide is impressive.

In other Apple news, they added Movies to the iTunes store and updated the Shuffle, Nano and iPod Video with a few minor revisions.

For what it’s worth, one of the announced software upgrades is CoverFlow, previously a 3rd party app that Apple just recently bought out and rolled into iTunes.
