Making presentations in the corporate world is definitely one of the staple tasks in any office, and this is where the USB Wireless Presenter comes in handy. Not only does it allow you to scroll through your presentations as you like, it also comes with a laser button that helps keep the focus of the audience on one particular segment of the slide at the moment. Being wireless also brings along the benefits of moving away from the computer/notebook to have a closer interaction with the rest of the audience. The USB Wireless Presenter retails for $22 each.
