Universal because you can sit any laptop on it but particulary matched to the brushed aluminum apple laptops like macbook pro or macbook air. The stand is good because it increase slightly the aount of desk space you have by having space under the laptop but for me I like that it lifts my laptop screen to very much the same level as my secondary monitor. If you are only using this laptop then combining this with a keyboard allows you to have a 'grown up' working setup. Higher monitor and separate keyboard feels much more relaxed. There are secondary benefits that allow a hot running laptop to get more circulation around it. So if your laptop runs hot then don't put anything under the stand.

This is a review of the apple keyboard (wired) suitable for all apple products like (*) macbook pro or apple macbook air. As a serious alternative to the bluetooth keyboard, do you really need bluetooth?
* ipad iphone (devices wothout a usb port) etc- you will need extra device to get usb connectivity so go for bluetooth.
