Panasonic's 20-inch 4K Windows 8.1 Tablet Ships To US Users In January For $6000
If neither of those seem like huge drawbacks, the Toughpad 4K UT-MB5 packs a 3840x2560 resolution display (thats' 230 pixels per inch at a 15:10 aspect ratio), Intel's Core i5-3437U vPro processor, NVIDIA's GeForce 745M GPU, and Windows 8.1 Pro. There's also a spacious 256GB SSD, 2GB of VRAM, 8GB of system memory, 802.11a/b/g/n Wi-Fi, Bluetooth 4.0, USB 3.0, an SDXC card slot, docking connector, and a 720p webcam on the front.
At 0.49-inches thick and 5.27lbs., it even makes the original iPad feel dainty, and given the two-hour battery life, you better stick pretty close to a wall charger. But look, it's a 4K tablet!
