In other words, one of those "your ideal DAP" threads. But you have to have in mind what you reasonably think would be successful. In my mind, the only way to beat the iPod is to advance the game to a new sphere, so I think new functions have to be added, transforming the player in more than just a music device. Video is the obvious one, though mostly for music videos. Not that I want necessarily that, but I think that's one way to generate buzz and have the "wow" effect. I would also add, for the sake of it, Java-based games, like the cellphone ones. And then, the killer app, in my mind, would be wireless connection and the availability of a special Web music and music video store configured only for access directly on the player. The connection could be two ways: by wi-fi, using hot spots, or by some form of cellphone connection. I would also add a microphone to the player and some way of recording snippets of music that could be then used by special software that, when connected to a central server, would identify the song and offer it for sale. (Cellphones already offer that.) Giving the chance of people buying music wherever and whenever they want, and without needing to use a computer, I believe, produces the "cool" factor that is needed to dethrone the iPod. Also, the wireless connection could be used for somebody to stream music or video to others with the same player, and to swap pictures. If the company was Sony, I would also add connection to the PSP (imagine having a Walkman as a storage device for videos that would be shown on that gorgeous screen of the PSP?) and give a simpler version of Lumines as a preloaded game.
