Hugh Pickens writes writes: "David Pogue writes that with Windows 8 Microsoft has made a billion-dollar gamble that personal computing is taking a new direction and that new direction is touch. Using a series of fluid, light finger taps and swipes across the screen on a PC running Windows 8, you can open programs, flip between them, navigate, adjust settings and split the screen between apps, among other functions. It's fresh, efficient and joyous to use—all on a touch-screen tablet. But Microsoft expects us to run Windows 8 on our tens of millions of everyday PCs and although touch has been incredibly successful on our phones, tablets, airport kiosks and cash machines, Pogue says touch will never take over on PC's. The reason? Gorilla Arms. There are three big differences between tablet screens and a PC's screen: angle, distance and time interval. The problem is "the tingling ache that [comes] from extending my right arm to manipulate that screen for hours, an affliction that has earned the nickname of gorilla arm." Some experts say gorilla arm is what killed touch computing during its first wave in the early 1980s but Microsoft is betting that Windows 8 will be so attractive that we won't mind touching our PC screens, at least until the PC concept fades away entirely. "My belief is that touch screens make sense on mobile computers but not on stationary ones," concludes Pogue. "Microsoft is making a gigantic bet that I'm wrong.""
