All the processor does is decompress a JPEG file or maybe run some Java scripts. Intel and everyone in the business know that if something doesn't change, the entire industry is in trouble. Unfortunately, people have been slow to add video to their computers, and there is no evidence that this is changing. Intel has been promoting video phones for years.

There doesn't seem to be a compelling reason to use video. But there isn't the same lure as with sound add-ins. Game technology has been the driving force behind personal computing. All the cool graphics, the need for color, and the need for sound derive from gaming. Computer games have yet to integrate video into their technology, and this is the reason video has not taken off as was hoped.
