Opera is known for originating many features that are later adapted by other Web browsers. Despite these factors, Opera has captured only a small fraction of the worldwide personal computer browser market. It does, though, have a stronger market share on mobile devices such as mobile phones, smartphones, and personal digital assistants. Editions of Opera are available for devices using the Maemo, BlackBerry, Symbian, Windows Mobile, Android, and iPhone operating systems as well as Java ME-enabled devices.
