keynote

Are you asking how to install Keynote (the app) or how to transfer Keynote presentations?

In the first case - you don't. Call up the AppStore app on your iPad and purchase it from there. In the latter case: When you connect your iPad to your PC, there's a section called Apps in iTunes where you can transfer Keynote files between iPad and PC.

Unfortunately when importing presentations to the iPad, a lot of things go wrong.

1. Many Keynote fonts are not supported on the iPad app.
2. Some images are not imported.
3. It will not import Keynote 11 files from the iMac.

These problems need to be fixed, as if the iPad is to be used as a serious productivity tool by teachers, one must be able to import existing presentations smoothly.

Not sure what you mean by "Keynote 11" - there's no such product (yet) ...
