At todays ASUS press conference here in Las Vegas, chairman Jonney Shih unveiled a new line of low-cost Android smartphones, dubbed Zenfones. The devices, which come in a range of 4-, 5- and 6-inches, have dual-core Intel Atom processors inside and run a skinned version of Android 4.3 that ASUS is calling Zen UI. Apart from a focus on imaging software, Shih didnt elaborate too much on what users could expect from that interface.
