The HP 200LX — The Finest Pocket Computer Ever Made
The HP 200LX, released in 1994, is widely considered the finest pocket computer ever produced — a DOS-compatible palmtop running a full suite of productivity software including Lotus 1-2-3, a database, a contact manager, and a calendar on two AA batteries lasting weeks. Its clamshell design with a small but usable keyboard, combined with full DOS compatibility and HP’s legendary build quality, created a machine that serious mobile professionals used for years after its discontinuation. The 200LX ran any DOS software, communicated via a built-in modem, and could connect to desktop PCs — an extraordinary package in a device smaller than a paperback book.
