What's cool about it: Launched earlier this year, this device serves as Dell's first 2-in-1 version of the XPS 15. Along with its 360-degree hinge for folding the display, the laptop offers differences from the clamshell XPS 15 including a form factor that is 5 percent thinner (0.63 of an inch thick). Dell says that makes the convertible XPS 15 the thinnest 15-inch 2-in-1 on the market. Even with that slim profile, Dell has managed to include quad-core Intel CPU options (eighth-gen Core i5-8305G or Core i7-8705G) that are integrated with discrete AMD graphics (Radeon RX Vega M GL) -- one of the first deployments of a processor integrating Intel CPUs and AMD GPUs. In addition, the XPS 15 2-in-1 offers up to 15 hours of battery life.
