laptop

A portable personal computer housed in a clamshell enclosure, integrating an LCD screen, physical keyboard, and trackpad on a base half that folds onto a top half containing the display. Built around a system-on-chip or processor with RAM, solid-state or spinning-storage, a rechargeable lithium-ion battery, Wi-Fi and Bluetooth radios, and USB/Thunderbolt ports. Designed for mobile use on a lap or desk — lighter than a desktop but self-contained. Persisted through electronics manufacture, global retail supply chains, and consumer replacement cycles; obsolescence is planned both in hardware wear and software update cutoffs.
