From The Register and Tech Digest:
Miminalism is the key here – the Play has no screen and just a single joystick for control. It plays MP3, WMA and ASF files for up to 12 hours on a single charge of its built-in battery, has five equaliser pre-sets and can support up to four playlists or play through randomly in shuffle mode.
No screen and just a joystick control? How can you navigate through menus then?
The Asono Play uses different sounds to let you search through folders and choose different playing options. This really tackles the issue of lack of screen space investigated by Brewster and Cryer to an extreme level.
I’m not sure how easy this would be to use, but I guess once you got used to the different sounds and what they meant, it would be pretty cool.
