Apple's iWork suite consisting of Keynote, Pages, and Numbers is very similar to Microsoft Office's PowerPoint, Word, and Excel; Apple brought iWork to the iOS platform last year, extending its reach from Mac OS X. Microsoft, on the other hand, has not yet brought their Microsoft Office suite to the iOS platform, albeit it is available on the Mac OS X platform.
This will all change soon, as Microsoft’s Czech division has reportedly stated that Microsoft Office for iOS is set to launch in March of 2013:

Microsoft Office is by far the most popular productivity suite for PCs and it should be interesting to see how it impacts mobile devices such as the iOS platform. The iOS App Store offers a variety of Office-like software for very cheap prices, so Microsoft would have to price their mobile suite just right for people to consider the purchase. Apple’s mobile iWork suite currently sells for $9.99 per application – a grand total of $29.97 for the mobile suite.
UPDATE: Microsoft has stated that the comments made by their Czech division relating to a March 2013 release date of Microsoft Office for iOS were false. More here.
