[ Ars Technica ] Peter Bright:
The fine-looking 4K screen starts at $1,799, which gets you 8GB RAM and a 256GB SSD, as well as the discrete graphics. I think this is probably the best-rounded system.
The 15.6-inch IPS LCD can be equipped with an optional 4K display with a pixel format of 3840×2160, good for a resolution of 282 ppi. And the massive number of pixels are powered by a discrete NVIDIA GeForce GTX 960M GPU with 2GB GDDR5 VRAM. The XPS 15 posted some solid benchmark numbers, beating the competition in most.
The thin bezels around the display make the XPS 15 look nice, nicer than most MacBooks (Airs and Pros) except for maybe the 12-inch MacBook. The only weird feature on the XPS 15 is the location of the webcam: it’s underneath the display. I guess the bezel was too thin to put a camera up there.
