Looks like Asus is planning a Mini version of their PadFone. Some benchmarks show a device with a model PadFone T00C, similar to the model of their hybrid PadFone devices.
This PadFone Mini looks like to be a 4-inch device with a 275 PPI screen, which is slightly better than the Samsung’s GS 4 Mini. It’s also powered by a quad-core processor, the Snapdragon 400. It’s also running Android 4.3, so the software side of things is top notch.
