If huge improvements in cooling are what you are looking for, a non-powered device would not be the way to go. On the other hand, if a low or no noise solution is a requirement, this device fits the bill. Add in the fact that you don't have any moving parts to fail or an external power supply, and the device becomes a little more attractive. One or two degrees may not seem like a lot of improvement in cooling but every bit helps. In addition, everyone has seen the newer keyboards on the market with a slight amount of rise to the rear to help reduce arm and shoulder strain. This device puts the notebook on a slight incline and helps reduce some of the strain, which should allow for longer use of the notebook, without putting your body at risk of things like Carpal Tunnel.
