The 12 Best Gadgets You Didn’t Buy
Kohjinsha DZ Series Dual-Screen Notebook
In 2009 Kohjinsha released its DZ Series, a notebook with two identically sized 10-inch screens that sat next to each other on top of its deck. The DZ, which was also sold as the Onkyo DX, was the ultimate multitasking device, but Japanese consumers didn't buy enough of them to keep the line going. While a new generation of portable USB monitors makes it easier to take a second screen with you, there’s nothing like having one built directly into your laptop.
