Used to bring the laptop up to the same height as the second monitor and free up space. The desk is small so it is great to be able to store the wireless keyboard and mouse under when not in use and free up surface space. In addition the holes improve airflow under the laptop.
We put a 28" flat screen tv on it so we could put a Uverse cable box under the tv and it is working great. It even got it up higher so we can see the TV much better.
