The Dell Precision 5520 checks almost all boxes for a professional 15-inch workstation. Using the base principles of the XPS lineup, the Precision 5520 is one of the most portable and well-designed workstations we’ve ever come across. With the use of high-quality premium materials, the laptop is not only super rigid but also thin and light. And thanks to the thin screen bezels, the machine fits into the 14-inch category with ease. The input devices are comfortable as well and we are not talking only about work on the go.
