Here is the Firefly from Vestalife, which is actually an iPod and iPhone speaker dock that features a built-in subwoofer and a digital amplifier to offers good quality of sound. The device also comes equipped with a remote control, and the battery saving automatic shut-off feature.
The speaker is powered by a rechargeable lithium-ion battery or AC power supply. You can also connect the Firefly to CD players or MP3 players via an auxillary-in jack. No word on pricing at this time. [SlipperyBrick via iPod and MP3 Players Blog]
