With the Atrix HD cat out of the bag for almost a week, Motorola is finally getting around to giving the Android phone the offical treatment.

Specs for the device are identical to the ones that were leaked previously: The device features a Gorilla Glass-protected 4.5-inch, 720p high-definition display, 8-megapixel camera, 1.5GHz dual-core processor, and will run Android 4.0. No Jelly Bean, sadly. Another notable bit of info: At 8.4mm, the Atrix HD is bit thinner than the 8.9mm Droid Razr Maxx and far thinner than the 10mm Atrix 2. Clearly, Motorola’s engineers have made some big improvements.

The device is also the first from Motorola to feature the so-called “Circle Widget”, a homescreen addition that allows easy access to the weather, time, data usage, and battery status. While the feature sounds great in theory, we’ll withold judgement until we actually test it out.

Unfortunately, confirming previous reports, the Atrix HD’s battery features a 1,780 mAh battery, which, as we noted before, is sure to cause some issues with the device’s large display.

Available July 15th, the Atrix HD will be exclusive to AT&T, which gives it access to AT&T’s 4G LTE network. (It’ll come to Canadians via Bell.) What’s surprising, however, is that the device will only sell for $100 on-contract, which is half of what you’d expect it to cost.

And here’s a question: Is anyone really going to pay attention to Nokia’s Lumia 900 when the much more capable Atrix HD is sitting right next to it? We’re not so sure.
