One of the issues I have had with the new Keynote for the iPad is the lack of font support. And while I am not a fan of prebuilt theme use in Keynote (or PowerPoint), iPad users have some new option. iPresentee, a long time developer of Keynote themes has released: Keynote Themes for iPad. This set of 33 themes are developed to fit the limited font set of the iPad and should make transferring Keynote presentations back and forth between your MAC and your iPad much easier. Again, I am really not a huge fan of prebuilt themes, but they do have their place in more classroom type environments. The set run $25. Considering Keynote for the iPad is only $9.99, paying $25 for themes may be a bit steep. Also keep in mind that out of a set of 33 themes there are only 3-5 that are really practical for effective presentation.
iPresentee also makes themes for iWeb, Keynote ’09 and Mac Mail.
