E Fun's Apen Touch8 pen is shown at the International Consumer Electronics Show in Las Vegas, Tuesday, Jan. 8, 2013. Many people who have tried Microsoft’s new Windows 8 operating system without a touch screen have hated it because of the inability to use touch and swipe commands to get things going. Now a company has made a digital pen to allow people to use Windows 8 on their old monitors for less than the cost of buying a new touch-enabled computer. (AP Photo/Jae C. Hong)
