The Jornaa was a line of personal digital assistants or PDAs manufactured by Hewlett-Packard computers. The Jornada was a broad product line that included Palm-Size PCs, Handheld PCs, and Pocket PCs. The first model was the 820, released in 1998, and the last was the 928 model in 2002 when Compaq and HP merged. The Jornada line was then replaced with the more popular iPAQ model PDAs. All Jornada models ran Microsoft Operating Systems that were based on Windows CE.
