This is a myopic take.

I've found iPads to be fantastic presentation tools.

Having an ipad on a conference/convention booth is amazing - airplay my rotating content to a big screen, and when someone walks up I can grab the ipad to delve into details based on the conversation.

Early on (first gen ipad) I had a whole client team nickname me "the ipad guy" because I showed up and presented across a few ipad apps where I could pinch, zoom, and annotate live instead of showing a vanilla PPT file.
