If it takes you more than 5 seconds to find the power button on a laptop or other gadget, the designers have failed. I've seen too many notebooks with the button on the front, which is not only unintuitive, but makes it too easy to accidentally turn off your system when it's sitting in your lap. Motorola placed the power button for its Droid Xyboard 8.2 tablet on its back, which amazed me because everyone ridiculed the original Xoom slate for this very issue.
And here's a note to makers of smartphones with larger-than-life screens. Make sure you put the power button on the right instead of up top so we don't stretch our fingers out of our sockets.
