MojoKid writes: Also known as "Project Sputnik," Dell came up with the idea of offering developers a variant of their XPS 13 notebook running Linux and launched its first models over three years ago. Now in its 5th generation, Project Sputnik is still going strong today with the latest models combining Ubuntu 14.04 with Intel's Skylake processors. To kick off its newest generation of Developer Edition laptops, Dell is offering three Core i7 XPS 13 configurations, including two that feature 16GB of RAM. Dell said it also plans to add a Core i5 option to the Developer Edition lineup sometime down the line. Dell is seeing increased interest from customers and in addition to the XPS Developer Edition, Dell offers Ubuntu on its Precision 5510, 3510, 7510, and 7710 mobile workstations, as well as its Precision M3800. Cost of entry into Developer Edition territory runs $1,550. What that gets you is a 13.3-inch QHD+ (3200x1800) InfinityEdge touch display powered by an Intel Core i5-6560U processor, 8GB of LPDDR3 1866 RAM, and Intel Iris Graphics 540.
