So I've really been using my 13" MBP in bed, on my lap a whole lot lately, and I feel like it gets too hot sometimes/is uncomfortable to use in my lap. What are some good, cheap lapdesks? How does this one look --> http://www.amazon.com/Logitech-Note...3?ie=UTF8&s=electronics&qid=1253249056&sr=1-3 $30, not bad. Reviews seem pretty good. What do you guys think??
