Included version 1.2 updates for each $10 app: Keynote-to-PowerPoint format export, extra presentation animations and Keynote to MobileMe iDisk support; Numbers spreadsheets convertable to Excel format; and Pages allows for displayed word count and .txt opening support. Plus more!
What bothers me about most videos using autotune is that they go overboard with the effect. A bit of subtlety works so much better. Take this short clip of the iPad keynote for example. It's definitely worthy of imitation.
