We've seen a number of hot smartphones hit the market recently, including the HTC Thunderbolt, Droid Charge, and others. Although each phone has its own appeal, there are also a lot of similarities among today's hottest smartphones—most have a 1GHz processor, at least 16GB of storage in one form or another, at least a 4-inch display, etc.
Sprint and Kyocera weren't content to simply offer more of the same in terms of smartphones. That's where the Kyocera Echo comes in to play. This smartphone features an innovative design with not one, but two, screens. The Echo is the first dual-touchscreen Android-based smartphone to hit the market, and it certainly brings a new experience to Android.
