If you've ever worked outdoors with your laptop, you know how critical it is to get some shade for your screen so you can actually see it. Instead of buying a laptop visor, pick up an IKEA storage box for $5 to serve as your laptop's foldable shade.
DIY Photography posted this tip from photographer Paul Adshead. You don't even have to do anything to the Drona box -- just unfold and stick a laptop up to 15-inches in there.
I have this box in my laundry; it's pretty sturdy and folds flat. Whether you're a photographer working on location with your laptop or otherwise need to work in the sun for a bit, this is an inexpensive solution.
