I use my sleeve as a lapdesk, too, when I'm on the road. at home I use one of those beanbag lapdesks when I'm working in a recliner, and an iCurve at my desk. But I'm thinking about maybe getting a Laptop Desk 2, which doubles as an elevated deskstand and a lapdesk. (You need an elevated stand to raise it to proper ergonomic height and avoid neckstrain, as well as permitting air to get under the Macbook and cool it.) It doesn't have a powered fan , but it does have grooves which supposedly let air circulate underneath when it's on your lap. Unfortunately, the web link I had for it doesn't seem to be working, ,which isn't a good sign, I guess.
