Aldus Corp has introduced release 2.0 of its Persuasion desktop presentations program for the Apple Computer Inc Macintosh: the company reminds us that Persuasion is a complete desktop presentations toolkit for outlining, word processing, drawing, charting and formatting presentations, and that it can produce output for black-and-white or colour overheads and 35mm slides, as well as speaker notes and audience handouts, but fails to say what new features are offered in the new release; the thing is $500, $75 to Persuasion 1.0 users.
