At 7.1mm-thick, Motorola Droid Razr is world's thinnest smartphone

Smartphone season unofficially started last week with the release of the iPhone 4S. As Android phone makers try to capture their share of the lucrative Christmas market, the volleying for differentiators takes different angles to be as appealing as possible to consumers.

For the Motorola Droid Razr, their gimmick is thickness (or lack thereof). This "impossibly thin"smartphone is equipped with a stainless-steel core, a Gorilla Glass screen and a nanotechnology Splash-guard. Motorola Mobility President Sanjay Jha said the 7.1mm-thick device is the world's thinnest.

Here are some of the specs:

• Android 2.3.5 Gingerbread OS
• Syncing through MotoCast
• 4.3-inch Screen
• qHD Resolution with Super AMOLED
• 1.2GHz Dual-Core Processor

The company described MotoCast as the most important feature on the phone.

"You can stream content from your computer straight to your pocket (or purse) so your personal content is always within reach," the company said in a press release. "And, because you don’t have to upload to a third-party site, you’re saving time while gaining peace of mind. That’s right — your files stay safe because they stay with you."

A 2-year Verizon contract puts the phone at $299.99. It will be available early next month.
