The latest release for the X-Box is also a non-gaming release. Xbox Music Mixer is a Karaoke add-on to the gaming console, available for $40 and including a microphone, Microsoft hopes to appeal to more mainstream consumers than just hardcore gamers.
Another feature in the karaoke add-on is a picture viewer that enables pictures to be copied from a pc to the x-box and creating slideshows.
Perhaps this will be particular popular in Japan, given their affinity for karaoke bars? ;)
