Abstract:

Is today's OpenOffice good enough for the enterprise? For most jobs—word processing, presentations or spreadsheets—the answer is yes. Compatibility with Microsoft Office isn't a problem unless sophisticated macros are involved. Interoperability, the greatest hurdle to conquer on the way to adoption, is almost a nonissue. OpenOffice even offers features missing in Microsoft Office, like PDF or Flash data exports.
