iWork is perhaps the most exciting offering that makes Apple iPad Tablet a real cool gadget to have. In addition to all the functions such as eBook Reader, Photo Viewer, Web Browsing, Managing Music and Movie Collections etc, iWorks makes the Apple iPod table a real productivity tool.
Phil Schiller announced in the big iPad unveiling event that Apple is offering a completly new version of iWorks specifically designed for iPad. Each application in iWork has an impressive UI designed to make it easy to work with documents, slid shows, spreadsheets etc. Each application integrated the Media inspector for quick access to your music, videos and photos.
Pages
Like its desktop counterpart, you can create publications with standard text and images. However, you can also use gestures (pinch for example) to move images around the publications and more. What’s interesting about this feature is that it could make placement possibly easier than using a mouse with the desktop version, as long as the proximity “drop” is accurate.
Slide Shows with Keynote
From what we could see during Apple’s presentation, you can rearrange slides by pressing on each and then move them accordingly. In addition, there is a unique slide management feature in that you can tap multiple slides, and with a gesture, it moves the slides into a bundle. This should definitely be a timesaver for many folks. Lastly, we learned that the iPad also has an optional cable for connecting with a projector, making it easy to use the device as your primary presentation tool.
Numbers
From what was demonstrated at the Apple Event, the iPad version of Numbers automatically displays fields and sums (which then infers what the output will be). Otherwise, this version seems relatively comparable to its desktop partner.
