DLP's primary advantage that the user will notice is portability.
The image quality is close - screen door means you are sitting too close, or you're using too low a resolution - Contrast is close with latest technology Seiko Epson LCDs.
LCDs are more efficient (more light on the screen for the power-in), so this allows some combination of brighter, cooler (with better reliability, usually), or more quiet.
Unless you carry it on airplanes frequently, I see no reason in the world to pick DLP.
Compare the video quality of XGA LCD-based units, and pick the one that fits your eye and budget.
