Having a large screen doesn't necessarily mean an ultrabook has to be inconvenient to use and carry. The Dell XPS 13 notebook line features 13-inch HD displays, but its models aren't much bigger than computers with 11-inch screens, as they weigh less than 3 pounds and are only 12 inches in length. The Gorilla Glass display almost runs from edge-to-edge so there is no wasted space in the upper panel. This Dell ultrabook maintain their stylish appearances even after continuous use. The glass is notably scratch-resistant and the outer shell is constructed from durable metals and composite materials. The high level of protection these features provide means the notebooks can be used in practically any environment without being any worse for wear.
