Ability to see presenter notes on the iPad screen.
One exception is charts.
PowerPoint only creates simple charts without the help of Excel.
Keynote, on the other hand, has no problem creating nice-looking charts.
The level of detail Microsoft added with fonts and shapes pays off in PowerPoint.
Keynote can do some of this, but not nearly as well as PowerPoint.
If you should probably make a splashy presentation, PowerPoint is the best choice.
But what about giving that presentation?
PowerPoint relies ondisplay mirroring, which means the iPad screen is duplicated.

This whole process seems much smoother in Numbers.

Free to download for all iOS owners.
iWork is free to download for all iOS devices.
All things being equal, though, it’s hard not to give iWork the crown.
