One of the biggest differences between the laptops in our comparison is on ports. Or in the case of the MacBook, port. The MacBook has just one port, USB-C, which must handle all connections, including power. An adapter will be necessary for any other types of connections, and the need to juggle between charging the laptop and any other external connections should be a consideration for potential buyers. The XPS 13, meanwhile, has a USB-C port and also comes with two USB-A ports and an SD card slot.
