Ultrabook

Ultrabook is a specification and trademarked brand by Intel for a class of high-end subnotebooks designed to feature reduced bulk without compromising battery life. They use low-power Intel Core processors, solid-state drives, and unibody chassis to help meet these criteria. Due to their limited size, Ultrabooks typically omit common laptop features such as optical disc drives and Ethernet ports. Ultrabook is a portmanteau of words ultraportable and notebook.
