I hope this is the right place... I am contemplating the purchase of an iPad to complement my forthcoming 27" iMac, and I have a question about the functionality of Keynote for iPad. I am a teacher and would like to incorporate Keynote presentations in my lessons (most teachers at my school use Powerpoint). I understand that I can create Keynote presentations on the iPad and then sync them back to my iMac (which will also have iWork), but more importantly, am I able to use my iMac to create a Keynote presentation, sync it to my iPad, and then show said presentation in the classroom from my iPad? Or does the iPad only show slideshows and presentations completed ON the iPad itself? I hope this makes sense!
