The reason why LCoS is a good display technology is one of its technological traits known as fill-factor. For a given amount of space to create a 'pixel' there is waste. This wasted space is the result of providing a gap between this pixel and the pixels adjacent to it. The less wasted space the higher the fill-factor.
LCD has the worse fill-factor of any fixed-pixel display technology. In fact, many relate to looking at an LCD image like looking at a photograph through a screen door on your house. Hence, the 'screen door effect' (aka SDE). Typical fill-factor for LCD is around 50-60% (used for image, rest is wasted space).
DLP has a fill-factor of around 89-90% (unless it has changed recently) and LCoS more along the lines of 93-94%. One of the things about the fill-factor between DLP and LCoS is their leading edges. DLP has a sharp (some say crisp) leading edge, but this could be taken to making the image pixelilated. LCoS has a more softer leading edge and often is said to produce a more film-like image.
But, with all competing technologies they have the strengths and drawbacks. For instance, LCoS (like LCD) has a rather low native contrast ratio while DLP is much better. On the other hand, you are not going to see DLP rainbows with LCoS (or LCD).
“The other one is a biggie, and it's something very noticeable in the videos: touch sensitivity is pretty bad. Using the virtual keyboard proved to be far too painful, and we're pretty sure it wasn't multitouch-friendly.”
