Two companies have released their visions for home-MP3-players. Diamond released their Rio Digital Audio Receiver which basically just streams music from the existing PC using phonelines as LAN cables.
But more interesting release is an MP3 player from a company called Request. Their player has 17GB harddrive which allows users to store huge amount of MP3 music in one device. Device is called as AudioRequest and it's priced pretty nicely, for $799..
