Apple's version of Microsoft Office. On the Mac App Store Keynote, Pages, and Numbers are $19.99 each and on the iOS App Store they are $9.99 each. With iCloud, the users documents are in sync with no effort on the user's part.
Because the apps are individually sold, users can pay only for what they actually use.
Student 1: I just bought Microsot Office from my college bookstore. It was $199.99 and I put it on my credit card.
Student 2: cool story, bro. I downloaded the iWork app Pages from the App Store for $9.99. I only payed for what I needed and I payed for it with real money.
