Laptop Steering Wheel Desk - This is not an item I would consider, but David Pogue's tweet about it led me to check it out. The comments and user uploaded pictures...brilliant! I can only imagine that the manufacturer might be annoyed, though.
"This has been a total lifesaver. It allows me to prop my sheet music against the wheel, allowing me to play the guitar with both hands while driving." by Brent
"The product description is incomplete. This doesn't need to just be used for laptops! I use it to chop vegetables, play solitaire, and roll dough for delicious croissants (at stoplights of course, I'm not dumb!). This is an amazing time saver for busy urbanites on the go." by Dan
