The other features of the P70 aren't necessarily new, but still nifty. There's a Pantone X-Rite color calibrator built into the palm rest of the laptop. To calibrate, just close the 4K IPS panel, and it runs. No need to find a darkened room or plug in a clumsy USB adapter.
Amazingly, Lenovo has shoehorned most of the same features into the P50, including the Thunderbolt 3, shared cooling, color calibrator, 64GB of ECC DDR4/2133, and up to three storage devices. It's basically a tinier version of the P70. You just have to give up one of those Thunderbolt 3 ports.
