My use of the Ipad as a teaching and learning tool ended up being largely behind-the-scenes. The Ipad is an incredibly convenient way to read electronic documents. Whether it was class readings or student papers, I was able to reduce my reliance on paper. I appreciated the increased portability and found that e-annotations are actually superior for my long-term personal filing system. I also valued having electronic copies of my text books. Though I only probably accessed them a half-a-dozen times, it is really nice to have a back-up copy available literately at your fingertips.
The Ipad was also a useful tool in the classroom, but my usage there was more ad-hoc. The value-added for using the Ipad to project lecture slides was minimal. Instead, I ended up using it more for miscellaneous classroom needs. For example, the camera feature came in handy when I didn't want to copy down my notes not white-board by hand. the Ipad also ended up being a great debate timer for formal debates in my public policy class. The Ipad even made a jeopardy-style review game more lively with a special buzzer app. I will definitely continue to bring my ipad into the classroom -- you just never know when it is going to come in handy.
Overall, I definitely will continue to use the Ipad as a teaching and learning tool. This is particularly true since I expect the availability of education specific-apps to improve. I do envision myself using the ipad as a grade book someday, or an easy attendance tool. I didn't quite like the functionality of the existing apps for those purposes yet, but I'm sure it is only a matter of time.
