As a Mac person, I am partial to Keynote--rather than PowerPoint--for visuals whenever I do presentations for a group. This morning I had such a presentation to deliver to about 50 interscholastic team captains at Choate. For the first time I used an iPhone app as a remote control to drive Keynote. This had the advantage of getting me out from behind the laptop; before I had to be within range of the infrared sensor when I used the traditional white Apple remote control. The Keynote Remote for iPhone works over the wireless network, so I could be much more mobile in the lecture hall and move through my slides with ease. And all this for 99ยข!
