MobiSystems has announced the availability of OfficeSuite for S60 which allows for the viewing and editing on Word and Excel documents on your phone. Features of interest include reading and writing Word and Excel formats, spell checking, support for the RTF and CSV document format (which should be good for non Word users), support for undo / redo operations and support for embedded images and tables.

MobiSystems are offering an interesting trial proposition for the program. Users can use the view only portion of the program indefinitely, while the editing portion (or at least the Save function) is limited to a 30 day trial.

The program has it's own native document formats, but also supports (without conversion) . doc, .txt, .rtf, .xls and .csv. and allow you to convert between these formats (where applicable).

The supported languages for spell checking are English, French, German, Spanish, Italian and Dutch.

OfficeSuite will be competing with Quickoffice for S60 which has had the S60 platform to itself thus far. Both suites will have their relative advantages (for example Quickoffice includes support for viewing and editing Powerpoint files, but does have support for spell checking). Both systems are available for a 30 day trial which should be enough time for you to judge their relative merits.
