The Mi Pad wasn't Xiaomi's only announcement today. Following the Chinese company's first smart TV from last September, today it has unveiled a slightly larger model with a nice surprise: 4K for just CN¥3,999 or about $640! Like its affordable predecessor, this 49-inch TV comes with built-in Android (with MIUI TV skin), though you can easily side-load other TV apps. On the hardware side, you'll find a 4K 3D panel made by either LG or CSOT within a 6.2mm aluminum bezel, and underneath that lies a MediaTek MStar 6A918 chip (1.45GHz quad-core CPU, Mali-450 MP4 GPU) plus 2GB of RAM to drive all those pixels. On top of the built-in 8GB space, you also get to add up to 64GB of storage via microSD.
