Apple today announced a new 64-bit update for its iWork productivity suite on iOS and Mac. The update includes an all-around revamping of the interface, performance upgrades, and  a new unified file format for the suite.  As with its iLife apps, Apple has made iWork free  for new device purchasers.

Pages has a redesigned user interface with a new content-sensitive format panel on the right-hand side. Numbers now supports interactive charts so you can track over time. Keynote now has object-based animations and physics transitions.

Additionally, you can now share documents through iCloud and users can open them in the beta version of iWork for iCloud. iWork for iCloud also now includes collaboration features, so you can work with others to edit documents simultaneously over the web.
