NEW YORK (TheStreet) -- On paper, the Asus PadFone X mini is a terrific idea. In simple terms, it's an smartphone and tablet combination running on the Android operating system. It comes in two pieces - the phone and a slide-in, tablet-shaped cradle. Execution of that terrific idea is another story.
The PadFone X mini offers a number of firsts. It's the first smartphone marketed in the United States to run on an Intel (INTC) processor and it's the first device of its type to be sold by AT&T's (T) Go Phone prepaid service division. A much larger PadFone X model is also available on AT&T's Website.
To understand the PadFone X mini, we need to examine the parts separately. The smartphone half is small, black and basically not much different from other mid-range Android smartphones of similar size. It measures 5.2 x 2.6 x 0.5 inches, weighs 5.26 ounces and runs Google's (GOOG) Android 4.4 software. The phone works on AT&T's 2G, 3G and 4G/LTE bands and includes the usual Wi-fi, Bluetooth and GPS connectivity.
The X mini utilizes a dual-core, 1.6GHz Intel Atom processor mated to 1GB of RAM and 8GB of storage and it has a microSD card slot where you can boost it up to 64GB. The mini has a touchscreen listed as 4.5-inch FWXGA (Full Width XGA). That translates to 480 x 854 pixels and 218 pixels per inch (ppi). The back camera is 5MP with an LED flash and a 2 MP front-facing shooter. The rechargeable battery pack capacity is 2060 mAh and is user replaceable.
