The company demonstrated its combination smartphone and tablet device called the Padfone at the Computex trade show in Taipei on Monday.

The new is basically an Android handset with a companion touch-based tablet dock that has a rear slot for holding your smartphone. The concept is similar to , an Android phone that switches between a handset display and a webtop view when hooked up to an external keyboard and monitor.

Asus is currently showing off a 4.3-inch phone and a 10.1-inch tablet dock, but the company says it has not finalized the Padfone's specifications, according to . Pricing and availability were not announced.

Being able to seamlessly switch between the smartphone and the tablet dock is the idea. For example, if you are watching a video on your handset and switch to the tablet, the device will allow you to continue right where you left off.

Asus says the tablet also will display content in its native resolution as opposed to simply upscaling the smartphone's display. The tablet's larger battery can also charge the smartphone component, and the phone's 3G capabilities will be available when in tablet mode. In one Asus promotional video, the smartphone's voice calling features were still available when in tablet mode.
