The iPod may have legitimate competition on its hands if the Touch HDD ever goes from concept to reality. Designer Daniel Arango has created a conceptual portable hard drive that would be able to display stored data and feature touch controls.
Data stored on the Touch HDD would be accessed via Wi-Fi or by connecting the device to a computer through a USB cable. Stored pictures can also be viewed and used as a wallpaper for the hard drive's display. The iPod-killing feature of the Touch HDD is its ability to play stored music and movies. It seems almost inevitable that portable hard drives will become more functional in the future, and they will probably look and function a good deal like the Touch HDD. Your move, Apple.
