In addition to iLife '09, Apple announced a major revision to its iWork suite of applications. iWork '09 is available now for $79/single user and $99/family pack, or only $49 with the purchase of a new Mac. It begins shipping today.

Keynote
New transitions, chart options. There's also a new Keynote Remote app for the iPhone and iPod touch to control Keynote wirelessly with video preview that changes depending on orientation.

Pages
Full screen viewing of documents, dynamic outlines, and a new mail merge with Numbers, which can connect with tables and lists in Numbers. Pages will also offer integration with MathType and EndNote. Additionally, there's a new set of 40 themes coming with the app.

Numbers
Table categories and 250 new functions will make things easier to understand.

iWork.com
A beta of this will be announced soon - offering collaboration options for notifying other people that you've changed documents, and allow others to review and edit them online. This will be a fee-based service offered by Apple once iWork.com launches.

Since OS X 10.5.x is required to run the new iLife, Apple is also offering a package of OS X 10.5, iLife '09 and iWork '09 for $169. This "Mac Box Set" will ship in late January when iLife '09 ships.
