Pro Unique design
Like other laptops in the XPS series, the XPS 12 is not any different in the design department. It's a beautiful piece of hardware albeit a little strange for convertible laptops since it doesn't have anything that holds the screen and keyboard together. There's no latching mechanisms or prongs like in other similar devices. The screen slots in place and a combination of magnets, friction, and gravity holds it in place.
It may seem a bit unnerving at first but it works and it's very secure while still allowing the user to easily lift the screen off.
Con Works comfortably only on a desk or lap
When keeping the laptop on a flat surface such as a desk or one's lap, the viewing angles are good. But working with it in any other position (such as when lying down) you will have a hard time with the viewing angles. There's also the issue of the screen tumbling forward since it's not held in place by anything other than some magnets.
