Samsung Fascinate OS: Google Android Price: $299 with two-year contract, $199 after mail-in rebate
There's only one word for the Fascinate: Hot. It's lighter than the iPhone, curvier, has the same three-axis gyroscope for gaming and has a Super AMOLED screen technology, 16-gigabytes of onboard memory and a 5-megapixel camera with flash and 720p HD camera video. For some reason someone removed the front-facing camera that was present on the Fascinate's international version, the Galaxy S, but otherwise it's a really fun device that battles the iPhone to a draw. The Android 2.2 updates that make it a roving hotspot and give it Flash compatibility may present a slight edge, as evidenced by the Fascinate's AT&T version, the Captivate. While it doesn't come close to the iPhone 4's sales numbers, it's part of the reason Android's been chipping away at Apple's smartphone market share.
