We don't have TV, but we like to lay on a blanket and watch DVDs on the laptop.
This laptop stand will insure good stability and air flow.
Step 1: A Laptop, a Blanket, and A Tray
We also have a very nice and stylish looking tray, made of plywood and melamine. The designer thought it would look cool with only two raised edges (and I found it too). But the surface is very smooth and thus slippery. As a result, things slide too easily, and the tray is quite unusable, as such. (To find similar trays, see www.esprit.co.uk/, or www.cb2.com/family.aspx)
Fortunately, these two problems happened to nicely merge into a one solution.
