This laptop was announced at CES, but barely. They have now released full specifications, including options, which are actually quite interesting. The 4K panel, in particular, has a color gamut that fully covers AdobeRGB (100%). This means that, if the hardware and software are properly calibrated, it is compatible with the color spaces that both video and print professionals tend to target. The latter is quite difficult, because magazine publishers actually have a large palette. Even the Wacom Cintiq 22HD only covers around 72% AdobeRGB.
Outside of this, the laptop has one processor choice: a Skylake-based Intel Core i7-6700HQ backed with up to 32GB of DDR4 RAM. There are three choices in GPU: NVIDIA GeForce GTX 960M, 965M, and 970M. This could be disappointing for those hoping for desktop-class performance, although the 970M is pretty close to a GTX 680. It should handle games like Just Cause 3 and Rainbow Six Siege at around 50-60 FPS in 1080p mode. Basically, you are going to be dropping the 4K resolution down to about 1080p in games, but it's also a laptop and 4K in professional applications is quite nice. It also uses M.2 SSDs with PCIe 3.0 x4 bandwidth that communicates in the NVMe standard. They didn't say which one, or how large, but they claim read speeds of about 2.2GB/s.
They did not state pricing or availability. Its headlining feature is thickness — just 1.99cm for a 17-inch display. This explains the GPU, but also suggests a premium price.
