I'd like to say that I do most of my work sitting upright at my desk, but in reality, that's not always the case. You're more likely to find me curled up on the couch working on my computer, or propped up watching a movie in bed. I've also created makeshift work spaces in airports while waiting for flights, my kitchen floor, and even on the city bus. Of course, with all of this mobility comes poor posture, and more often than not, a hot lap.
The Lightweight Laptop Stand ($26) is perfect for use anywhere, and since it is so light, it's simple to toss in your bag and take anywhere. My favorite is the bright orange, but it also comes in fun pink and more serious gray or black.
