PC World tested this portable projector from HP, here's a short clip: "The smallest projector in the group of 16 that we tested for our April 2006 issue roundup, the 2.4-pound MP2210 ($1500, as of January 18, 2006) is easy to carry and provides most of the basic functions you need for making presentations. The one notable exception: It's the only projector we reviewed that lacks a built-in speaker. So unless your notebook's speaker can supply the sound your presentations require, you may need to pack a portable speaker for your road shows. The MP2210 has a brightness rating of only 1500 lumens, and it is better suited for small groups than for large conference rooms.."
