This may be great for projectors, but I think it's really dishonest to market it as a laptop stand.
Firstly, it's too small for many laptops, and the lip around the top means it's not practical to simply let your laptop overhang a little.
Secondly, even if your laptop does fit, the same lip makes it difficult to connect cables to any ports on the sides (or the front) of your laptop. Or to insert or eject CDs.
Finally, the tilt doesn't lock in position, so leaning too heavily on the keyboard could cause it to swivel - and send your laptop crashing to the floor.
If you have a projector, it may be suitable. But if you have a laptop, consider a Stagg COS10, Roland SS-PC1 or Kamstands KL-2 instead...
