Here’s an interesting iPod dock that actually acts as a dock as a secondary function. The CAVS IPS-11G Karaoke Station uses your iPod or MP3 player into a storage device for what’s essentially a portable home theatre system, complete with karaoke abilities:

“CAVS IPS-11G Karaoke Station is an innovative multimedia player that acts as a bridge between your home audio-video system and your digital device, such as iPod®, MP3 player, USB memory stick, USB hard disk, and USB card reader. … CAVS IPS-11G can play audio video files of MPEG, MPG, AVI, DAT, VOB, MP3, JPEG, MPG, GIF formats, and also the karaoke files of MCG-MP3 format. This does not mean that your iPod® or MP3 player must be capable of playing the audio video or karaoke files. Simply store the files in your iPod® or MP3 player. CAVS IPS-11G will then access your ipod or MP3 player and play the files into your home audio video system. CAVS IPS-11G will turn your ipod or MP3 player into a home theater system to enjoy music, photos, movies, and also karaoke sing along.”
