It's a dogfight review between two high-end Android devices on T-Mobile. On one hand, you have the Samsung Galaxy S 4G, with a 1 GHz Hummingbird processor, 4-inch Super AMOLED display, 5-megapixel camera, front-facing camera, large 1,650 mAh battery, and Android 2.2 with TouchWiz. On the other hand, you have the T-Mobile G2, with an 800 MHz next-generation Snapdragon processor, 3.7-inch display, Android 2.2, awesome physical QWERTY keyboard, and a 5-megapixel camera with a flash. They're both strong contenders, but only one can win. Part 1 of 2.
