Imagine an iPod speaker dock that only cost twenty bucks, allowed you to charge (and sync) while connected and was portable enough to pack in your pocket. The AirCurve, by Griffin, does just that. An acoustic amplifier that works with both generations of the iPhone, the clever seashell-like coil design collects sound output by the iPhone's tiny speakers and projects it out, making it perfect for the alarm clock or speaker phone functions. And it never needs batteries or a power cord, though it can be attached to your sync cable. Sounds pretty good right? $20, at GriffinTechnology.com.
