Yes, the iPad doesn’t do PowerPoint. It also doesn’t do Word.
When I wrote these posts, Office Mobile for Office 365 hand’t been released.
It does do Pages.
More interesting, however, is that it does UX Write. UX Write is my favorite word processor. I wish there were a Mac version. It may not work for you, but it works for me.
There are lots of other word processing apps for the iPad.
Oh, and Pages and UX Write both work on the iPhone and iPod touch as well as the iPad.
