The Sony Walkman has come a long way since the early days when they owned the market with the Discman and slowly lost ground to the iPod. Shown above could be the early illustrations of a new touchscreen Walkman to compete with the iPod Touch. The player would feature a 3-inch OLED display which as you can see from the scale compared to the hand would be smaller than the current iPod Touch. It would also include WiFi and built-in access to Amazon’s MP3 Store. Although it’s currently just a rumor, I think it’s a good idea for Sony to focus on a product like this in order to compete for portable music market share.
