In order to watch videos in my workout room on my TV, I take the iPod, in my hand, into the other room. Then I plug it into the connector to play on the TV. I am usually wearing sneakers, by the way. I guess really they are cross-trainers, but that doesn't sound quite right. The "net", by the way, is short for "network". Yeah, sarcastic, I know, but for people like me who have made their living on computers, well, we just make it work.
Here at my home office I have not felt the need for a wireless, or even a wired, network. I only have this one computer, and carrying the iPod to the workout room isn't all that much trouble. It is for a workout, you know! But the day will come when Apple discontinues the video iPod and I will have to invest in a wireless system. In the meantime, I'll sneaker net.
