Gizmodo has a bunch of pictures of portable video players, by companies hoping to create the next iPod. There is one glaring problem with this - the content. Have you tried ripping a DVD? As I discovered recently, it takes about 5 hours to rip 1 hour of video from a DVD on a 1GHz Powerbook G4. Absolutely no-one is going to do this for their own personal use, not even if it was one hour per hour. Of course, you can use these things for pirated movies off of Kazaa etc, but is there a source of legally downloadable video content? Well, yes, there is - porn websites.
So, hopefully these guys are all concentrating on one-handed operation. You never know, this could be a successful business model. As Jack Davenport's character on Coupling pointed out, the entire history of human technology has been driven by men's need to look at women's bottoms.
