Motorola Atrix 4G announced Tegra2 and 1GB of RAM

Alongside the announcement of the Samsung Infuse 4G handset, another impressive device was revealed at ATT Developer Summit today at CES. The Motorola Atrix 4G runs Android 2.2 and is the first to feature a dual-core Tegra 2 processor in the ATT lineup.

The device first leaked in early December with the name Olympus and has a 4-inch display of qHD resolution (540x960 pixels) and the impressive 1GB RAM. The 16GB internal memory can be expanded via microSD memory cards.

The Motorola Atrix 4G camera is 5MP still the standard for high-end smartphones these days. HSPA+ is the best the device can offer on the network connectivity side and a massive 1930 mAh battery is supposed to keep the whole thing buzzing for more than 9 hours of talk time. Surprisingly the weight is kept under control 136g is a very good achievement considering what's inside.

As an Atrix 4G accessory, Motorola is going to launch what they call a Webtop. It transforms the phone to a netbookishly looking device with a 11.6-inch screen, a full-sized QWERTY keyboard. Using the Webtop with the Atrix 4G will provide additional 8 hours of battery life, thanks to the 36Whr battery included in the unit.

Motorola Atrix 4G will start shipping in the first quarter of this year. Pricing is not yet revealed, but be sure that we will let you know as soon as details emerge!
