A trial version of Apple's all-new productivity suite, iWork '08, has been made available for direct download by Apple.

Introduced at Tuesday's media event at Apple headquarters, iWork '08 is a significant improvement on the preceding version, and features a new spreadsheet application which Apple calls 'Numbers'.

Apple is offering Mac users a free 30-day trial version of the software which it is making available for download from the company website.

“Pages and Keynote make it incredibly easy, and even fun, for anyone to create stylish documents and presentations very quickly”, said Steve Jobs, Apple’s CEO. “Numbers rounds out the iWork suite, which is far more intuitive and easy to use than anything else out there”.

Numbers works like Keynote or Pages, focusing on the final appearance of projects. It offers multiple features for data entry, including intelligent tables, readable formulas, and Excel import/export facilities.

Keynote was also upgraded, it now offers new text effects and transitions, and powerful new tools for using images in a presentation. Meanwhile, Pages received features for change tracking, new templates and a contextual format bar.

iWork costs £55 and is available via direct download from Apple here. The download weighs in at around 500MB.
