Black tech game changer- Mark Dean

Mark Dean is one of technology's top innovators. The computer engineer helped design the IBM personal computer, introduced in 1981, that became a staple on desktops. He, along with co-inventor and IBM colleague Dennis Moeller, helped develop the interior hardware that would allow computers to connect to printers, monitors and more. Ironically, the man who helped make the PC popular is now using only tablets, noting in a blog post, "When I helped design the PC, I didn't think I'd live long enough to witness its decline."
