Fortex AR-4i

     This my friends is the Fostex AR-4i, and what it does is take the iPhone video camera capturing experience a step farther.

While the iPhone 4 does a pretty good job of capturing 720p video, the sound leaves a lot to be desired. There's only a small built-in mic, and the sound is recorded in monaural. With the AR-4i, your soundtrack can reach impressive levels of stereo awesomeness. The unit consists of a slide-on device that connects to the iPhone 4 through the Dock connector. Inside the device, powered by a pair of AAA alkaline batteries, is a AD / DA converter. You can either use the two small plug-in powered condenser cardioid mics that come with the AR-4i, or plug your own professional mics into the 3 stereo inputs on the device.

And at $149 i think the price point is right to finally replace that Hi8 video camera that you've been dragging to all your special events.
