Keynote is a presentation software application made by Apple for its Mac OS X operating system. Originally announced in January 2003, Keynote is now part of the i Work productivity suite (which also includes Pages), with a retail price of 79 USD in the USA, 55 GBP in the United Kingdom and 79 EUR in other countries of European Union. The latest version, Keynote 3, has been built as a universal binary, allowing it to run natively on both Power PC and Intel processors.
