Khoi Vinh used Keynote to design AIGA New York’s treasurer’s report.

Keynote’s completely logical and intuitive approach to design is completely engaging and unexpectedly powerful, given how bare bones it is. Which, compared to the complexity of Adobe’s products, made the process of designing this document fun. That counts for a lot.

Bonus: In the comments, Laurence Frabotta links to a great set of Keynote templates [Powerpoint available as well] from Apple’s 2006 Student Scientific Computing competition.
