There arent many pieces of technological design that simply cant be improved upon, but the clamshell-style laptop computer caseintroduced by Grid Systems in 1982may be one of them.
Thats why the vast majority of the portable computers built ever since have used it. But for more than a quarter-century now, inventors have been trying to top it, with folding screens, screens on stalks, folding keyboards, two-screen clamshells, tri-fold clamshells, and more.
