The state of the personal video market today is immature. Solutions are found in abundance only in the kids' section of the store. But that will change. Expect the change to come very fast. Microsoft has made very clear that it wants you to watch TV while you are sitting on the train, stuck in traffic, or have ten minutes I line. And it wants you to do it with Microsoft technology.
Don't discount companies such as Apple, which has turned the music industry upside down with iTunes and iPod. I am certain you can expect a similar effect with an iVideo and iPod video device.
TV is not the same anymore—it's personal.
