The 3D display is pretty cool (especially since you won\'t need those dorky glasses), but there are so many other reasons to pick up the HTC Evo 3D as a holiday gift. The Android device offers a dual-core processor, a solid design, and good battery life among other things, and is sure to please any smartphone fanatic.The good: The HTC Evo 3D improves on its predecessor with a dual-core 1.2GHz processor and a larger battery. The Android Gingerbread smartphone also features a glasses-free 3D display and can capture 3D photos and video.The bad: The smartphone doesn\'t offer much internal memory, and call quality could be better. The glasses-free 3D display has limited viewing angles and depth of field.The bottom line: The 3D features are a fun addition, but it\'s the HTC Evo 3D\'s zippy performance and improved battery life that make this Android smartphone one of Sprint\'s best.
