I finally broke down and ordered a LapGenie. I would have bought one a long time ago, but at $139 my inner cheapskate just couldn’t quite take the plunge. Well I finally did, and I’m glad. It’s lightweight, sturdy, and comfortable. It supports the weight of my laptop, adjusts to a useful range of heights and angles, and I can squirm and fidget all I want to without upsetting the computer. I use it all over the place- couch, bed, and outside chair when the weather permits.
It seems to be well-made, so I expect many years of service. They have a 30-day money-back policy and a good warranty. It showed up five days after I placed the order- many thumbs up for the LapGenie.
