iWork wasn't the first thing that came to mind when thinking of the new features the iPad would have, but Steve Jobs thought of it and told Apple's design team to create a version specifically tailored to the iPad's strengths. A new version of iWorks now exists for the iPad, and it includes the same three apps that come with the full, Mac version of iWorks: Pages, Numbers, and Keynote.
The interface is engineered directly to the iPad's multitouch screen. Rather than floating palettes, the palettes on the iPad appear to be more of an "on-demand" feature. There's also a specific data-entry keyboard for Numbers, which shows off the flexibility of the multitouch interface.
According to reports so far, it looks much more powerful than a typical iPhone app.
Pages, Numbers, and Keynote cost $9.99 each.
So far there's no information on whether this will be ported to the iPhone/iPod touch.
