The Motorola Atrix 4G is now available from AT&T for $199 with a two-year contract.  But Amazon Wireless is offering the new 4G Android phone for $70 less: $129 at checkout with free shipping for new customers, $149 for an upgrade. 

The Atrix 4G is a mobile powerhouse, with a dual-core 1GHz Tegra 2 CPU from nVidia (like the Motorola XOOM), UMTS, HSDPA, HSUPA, and HSPA+ data connectivity, 16GB of flash storage, 1GB of RAM, and an array of wireless technologies including 2.4GHz and 5GHz 802.11n Wi-Fi and Bluetooth 2.1.

There’s also an optional  Laptop Dock which uses the Atrix as its CPU, giving you an 11.5-inch screen, full keyboard and touchpad.
