A good option for PC / Laptop www.airdesks.com (Score 2, Informative)

I would really recommend you take a look at www.airdesks.com , I found them a few years ago and the one I have has worked great for the last few years, I picked one up for my parents and they use it daily for their laptop. In addition I others I recommended it to for use during recovery from surgery swear by them as well. Not well advertised, pretty simple design but they work great. They even have a unit for use on a treadmill that I may be picking up soon.
