We’ve heard a lot about dual core in smartphones. Kyocera is going you one better with its Echo, the first dual screen smartphone we've seen make it past the product concept phase. Running Android 2.2 for the foreseeable, this smartphone may not be the be all and end all of Android devices, but we definitely like where Kyocera is going. Other manufacturers will follow. Now if they could just get that pesky twice the screens, twice the battery drain thing figured out. In fairness, the company does offer a secondary battery as part of the package... but who really wants to cart that around everywhere?
