If you use your iPad for work, there’s a good chance you’re interested in using Keynote, Pages or Numbers, too. The Mac Observer took the time to check out all three so you’ll know what to expect before spending your hard earned cash.

Keynote The Keynote app for the iPad is a necessary addition to the suite of apps for most users. Even if one is not often preparing formal presentations, it’s a great way to collect and manage information from the photo library — or view already created content in, say, PowerPoint (.PPT, .PPTX, .PPS, .PPSX) It doesn’t have the power of its big brother on the Mac, but it doesn’t need to. It is supremely sufficient. Full review.

Pages Apple’s iPad is a great device for watching movies and TV shows, listening to music and playing games; and thanks to apps like Pages, it works great as a content creation device, too. Pages for the iPad is a slimmed down version of Apple’s word processor and page layout application, and it works surprisingly well for on-the-go document creation and editing. Full review.

Numbers With Numbers for the iPad, Apple’s multimedia tablet is more than just a movie and music jukebox; It’s also a full-on number cruncher. It doesn’t offer as many features as its cousin on the Mac, but it’s perfectly suited for spreadsheet work when carting around a laptop is more hassle than it’s worth. Full review.
