Most of my presentations are done in the conference room in our office or at a customer's office that we reach by automobile.

After debating the LCD or projector issue, I decided on a LCD. We just purchased the Samsung 18.1" LCD and run it at 1024 x 768. Great viewing angle and supurb display. Same viewing area as a 21" CRT. We don't have to carry a projection screen with us (projecter don't do well displaying on a wall) or a spare bulb. The Samsung is an analog display so it works with a standard video card. I use it in combination with a new Micron PII 400MHz notebook.
