Summary: I've neaver used any of the powerpoint or any real application that this product was meant for. My computer monitor IS my TV so the problem was trying to \"mouse\" on my knee or the arm of the armchair. This product was a wonderful find. It was able to duplicate all of the functions that a normal mouse does. It also functions with my media player to control volume and tracks and stuff. I guess you can download software from the web site to assign the buttons to do any task you want, but I havent gotten into that. I've been using it for over 6 months on the origonal battery that came with it. At first I hated it because it was new to me and i was much faster with the armchair balancing act. But dont give up cause i soon forgot and now this feels more normal than a mouse. I was impressed and have recommended it to friends and relatives.
