While System76 sells brilliant Ubuntu-powered laptops and desktops, it is not the only game in town. Actually, believe it or not, Dell has long been a proponent of Linux, even before 'Project Sputnik'. Its Ubuntu-powered XPS 13 Developer Edition laptops have been quite popular, and for good reason -- they are built well and are very beautiful. Today, Dell announces a refresh with 7th-gen Intel Kaby Lake processors. The 13-inch laptop even gets a new color option -- rose gold.
