I now own two of these, when I was getting one for a friend, noticed Amazon had dropped the price down to 9.00. (I'm getting a spare!) I've owned a targus lapdesk for the past 4-5 years, I'm on #2.These are great, good ventilation, and the desk doesn't 'slide' around on your lap. (nor does the laptop slide around) thanks to the small rubber feet on these. Whenever I pull this out at a meeting, people ask- Where did you get that? I often have the computer on my lap and I've never noticed any heat buildup, so I know it's ventilating well.These are very lightweight and store easily in my laptop backpack, between straps & backpack makes a great support. My backpack went flying out of a jeep when I got picked up from the airport on a tight turn, (back passenger door open) backpack skidded from car to ground at 25-30mph.. but it landed on the strap side.. lapdesk helped protect the laptop, because it fired up just find after the landing!
