Custom Notebook Design

A desktop-replacement computer is a laptop that provides most of the capabilities of a desktop computer, with a similar level of performance. Desktop replacements are usually larger and heavier than standard laptops. They contain more powerful components and have a 15" or larger display. They are bulkier and not as portable as other laptops, and their operation time on batteries is typically shorter; they are intended to be used as compact and transportable alternatives to a desktop computer.
Some laptops in this class use a limited range of desktop components to provide better performance for the same price at the expense of battery life; a few of those models have no battery. These, and sometimes desktop-replacement computers in general, are sometimes called desknotes, a portmanteau of "desktop" and "notebook".
In the early 2000s desktops were more powerful, easier to upgrade, and much cheaper than laptops, but in later years laptops have become much cheaper and more powerful, and most peripherals are available in laptop-compatible USB versions which minimise the need for internal add-on cards. In the second half of 2008 laptops outsold desktops for the first time.
The names "Media Center Laptops" and "Gaming Laptops" are used to describe specialized notebook computers.
