Following our get together last month, and listening to Lydia wax enthusiastic about condensing her endless lecture notes (that change each year) onto her iPad, I began to download my day's lectures onto the device and dispense with the typed notes. This has proven very helpful in the classroom. It's easy to carry around and doesn't require that I flip through pages on a lectern. The one small issue is that it seems to turn off quickly and students must be patient while I fumble to recover the document. I'm guessing that there is a way to change the timing on that.
At the faculty technology showcase last week, the patient IT staff showed me how to use the device to project images onto the classroom screen - I'm deciding on which app to use for that - that's next semester's task.
