Dell on Tuesday released the Aero, an Android-based smartphone available now on its Web site.

At just 3.67 ounces, the company touted the Aero as "one of the lightest Android smartphones." It also includes a capacitive multitouch and a 3.5-inch screen housing a virtualized keyboard.

Pricing starts at $299.99, but Dell said the Aero is available for as low as $99.99 with a two-year contract from AT&T.

The graphite Aero comes equipped with a 624-MHz processor, a 5-megapixel camera with 8x zoom and 2GB of onboard memory with an expandable MicroSD slot. The phone's built-in GPS allows for geotagging within social networks over its 3.6 Mbps HSDPA band or 802.11 b/g Wi-Fi.

The Aero seems late to the Android party as it's still running on a highly customized Android 1.5 with features like handwriting recognition and Facebook loaded into the OS, according to Engadget.

This phone also comes with a mini USB stereo headset, which can be used for calls with its Send/End key. As of this writing, the super slim Aero is only available through Dell's Web site, as AT&T has yet to make the phone available for sale.
