iWork. The iWork apps on the iPad are excellent, and would cover way more than most users would ever need. I'm still in college and have to send in Word formatted documents, but I've written several essays, fully formatted, in Word format from Pages on iPad. It's excellent. The other iOS Office apps are rather lacking, but Pages, Numbers, and Keynote are easily some of the best office apps I've ever touched. Sure, there are more features in Word, and there are more features in the Mac version of Pages. But the iPad edition is more than plenty for most uses. It honestly blew me away when I first tried it after struggling with QuickOffice on an iPod touch.
