Leaked earlier as Motorola Dinara or the Atrix 3, the Atrix HD is finally on sales at AT&T. It is priced at $99 with a two-year contract with the carrier. The price is decent for a high-end smartphone, especially at its release time. However, in case you are looking for a bargain, Best Buy is offering the smartphone with a similar contract for $49.

AT&T started selling the Atrix HD on Sunday, July 15. The design of the smartphone looks inspired from Motorola's Droid Razr family. The smartphone comes with 4.5-inch LCD display boasting a resolution of 720 X 1280 pixels with a pixel density of 326 ppi. The device is 8.4mm thick and weighs 140 g. The Atrix HD is available in two colors - titanium and modern white.

The Atrix HD also boasts of a dual-core 1.5 GHz Snapdragon S4 processor with 1GB of RAM and 8GB of internal storage, along with a microSD card support of up to 32GB. It has 8-megapixel rear camera and a 1.3-megapixel front-facing camera.

The smartphone runs on the Android 4.0 Ice Cream Sandwich OS with MotoBlur UI on the top. The device also comes pre-loaded with Motorola's Circle widget that connects users directly to their AT&T accounts and displays information like data usage, free minutes, etc. The government-standard encryption protects confidential data like e-mail, contacts, and calendar schedule.

The connectivity features include 4G LTE, Bluetooth 4.0, Wi-Fi 802.11 a/b/g/n, microUSB v2.0, and a dedicated HDMI port.

The Atrix HD is apparently an alternative to Verizon's Droid Razr Maxx across AT&T. The Droid Razr Maxx is the best-selling Android smartphone at the Big Red. Motorola Atrix HD has the same potential to become one of the best selling smartphone at AT&T.

The reason behind the modest pricing of the Atrix HD is possibly due to the absence of Webtop apps and lapdock functionality. The original Motorola Atrix was released with as a premium product with docks that convert the smartphone into a netbook. Motorola has acknowledged that it removed the feature to keep production costs low.

Picking up the phone from Best Buy at a discounted price means that the buyers can avail of a hefty early termination fee, which can go as high as $325 with $10 exception for each month of service commitment completed. Buyers will have to opt for a minimum $20 a month data plan.

Users looking for a smart purchase will likely make a beeline for the Motorola Atrix HD. However, with smartphone biggies like Nokia ( with its recent Lumia 900 slash) also competing for buyers' attention in the same $49 bracket, it remains to be seen how Motorola will finally fare.
