ASUS left us wanting for detailed specs when it showed off the Padfone X at this year's CES -- thankfully, AT&T (its carrier) has finally spilled the beans about the 2-in-1 device. The duo's phone component has a 1,920 x 1,080 5-inch display, a 13-megapixel rear and 2-megapixel front-facing cameras. Similar to other Padfones, this handset (when docked) transfers info over to its accompanying tablet, which in this case has a 9-inch display with 1,920 x 1,200 resolution and a 1-megapixel front camera. As we've previously mentioned, the device will be able to tap into AT&T's fledgling LTE-Advanced network, but it can also connect to the internet via WiFi and transfer files via Bluetooth 4.0.Under the hood, the Android KitKat twofer boasts a 2.3GHz Qualcomm Snapdragon 800 chip, 16GB of internal memory (that's expandable, thanks to a microSD slot) and 2GB of RAM. Even if the phone serves as the hybrid's brains, though, they're each powered by their own battery: the handset draws energy from a 2,300mAh battery, while the tablet runs on a 4,990mAh power source. That's about the extent of what AT&T's willing to share, so we're still in the dark when it comes to the Padfone X's price and release date in the US. But, considering Ma Bell's LTE-A network is now live in some locations and ASUS CEO Jerry Shen promised a Q2 release, we'll probably hear about those details soon enough.
