Once upon a time, texting was a walled garden. Messages could be sent and received only shared between phones from the same carrier. Cell-based video chatting, still in its infancy, is in a similar segregated state. Video calls between phones are restricted to within a specific video chat platform, currently Apple's FaceTime, the Android app Qik, available on the two Sprint 4G phones (the HTC EVO and the Samsung Galaxy S Epic), and a new entry, Movicha (pronounced "moe-VEE-cha"), powered by a technology from a company called Damaka. I recently tested them all, and (risking once again being accused of being an Apple fanboy) the winner — clearly, literally and figuratively — is FaceTime by a wide margin. Read on for the details.
