I do powerpoint presentations all the time and use this computer. It is a little tricky to get the projector set up, sometimes the video card recognizes it as a monitor others as a tv.
As for the remote control, it works great. I turn the computer towards me and I can leave the screen up for cues or close it so it doesn't distract me. I use the "L" button(same as left click) to advance slides, I can't figure a quick way to go back other than hitting backspace on the computer or hitting the "R" button(same as right click) and then move the cursor, using the arrows on the remote, down the menu to previous and hit the "L" button.
