The most common use I have for the laptop stand is right on the desk. The position I have it set at in this photo allows for better positioning of the hands for typing. The rubber bar across the front gives a comfortable place to rest the wrist and hands. (No, my desk is not normally this clean!)
When I returned home I began my search in stores and on the internet for something that would be lighter and allow use in different positions. I was not able to find it in any of the local stores, but did find it on the Internet.
The laptop desk is made from aluminum and has 3 locking joints on each side that rotate 360 degrees and lock at 15 degree intervals. The unit has a built in double cooling fan that can be powered by the USB port (cable included). I have not yet found I need the cooling fan as my 17" MacBook Pro does quite well by itself and the tray that the laptop sits on is aluminum and wicks away the heat quite well. If you have ever used a laptop on your legs, you know that it can get quite warm. Just knowing this fact alone would be consideration for using a laptop desk. If you tend to use your laptop in bed then the laptop gets very hot when sitting on the bedding, which may severely damage your laptop.
The stand is very light (a little over 4 lbs), but is able to hold up to 30 lbs. It does not feel heavy at all. Its size allows it to hold a 17" laptop. Although you can make a mini desk with the proper leg adjustments, I not know how practical it would be to actually do regular work on the laptop in this position. I have found it practical to position my laptop when needing to reference a document on the laptop when deskspace was not available where I was. The mini desk postion may be nice ot use if you were watching a video.
Possible drawbacks: There is only room for a laptop, it would be nice to be able to hold something you may be transcribing. I saw one model that included a coffee cup holder. Can you imagine what could happen if you were using this in bed? Depending on the laptop, it could slide off the stand, so be careful if you are moving the laptop stand while the laptop is on it.

Below, I have included links to this laptop desk and others like it on Amazon. NOTE: I do receive a small percentage for sales through these links, but feel free to look for a model that may suit you better. I own the unit on the left. Although they look similar I can not attest to the strength of the other models.
