The world's thinnest slider phone

Thin isn't all it's cracked up to be, despite what Kirstie Alley might say, especially when it comes to phones. Nevertheless, Samsung claims to have come up with the slimmest slider phone of its kind, the "Ultra Edition SGH-Z720," which measures a wispy 0.54 inches thick and weighs just 2.8 ounces.

The phone's design is still wide enough to include a 2.1-inch screen, a 3-megapixel auto-focus camera and a second camera for video telephony, according to Fareastgizmos. Notable software features include preinstalled Google mobile search and Gmail, as well as support for Samsung tracking systems. But the phone is available only in Europe for the time being, so your cell phone diet will have to wait.
