Thirty years ago, IBM created the first personal computer running Microsoft's MS-DOS. Today, IBM and Microsoft seem to have very different views on the future of the PC.
IBM CTO Mark Dean of the company's Middle East and Africa division, one of a dozen IBM engineers who designed that first machine unveiled Aug. 12, 1981, says PCs are "going the way of the vacuum tube, typewriter, vinyl records, CRT, and incandescent light bulbs."

IBM, of course, sold its PC division to Lenovo in 2005. Dean, in a blog post, writes that "I, personally, have moved beyond the PC as well. My primary computer now is a tablet. When I helped design the PC, I didn't think I'd live long enough to witness its decline. But, while PCs will continue to be much-used devices, they're no longer at the leading edge of computing."
Dean's remarks continue a debate over whether we are now in a so-called "post-PC" era, in which smartphones and tablets are replacing desktops and laptops. Not surprisingly, Microsoft -- seller of 400 million Windows 7 licenses -- isn't a fan of that term.
"I prefer to think of it as the PC-plus era," Microsoft corporate communications VP Frank Shaw writes in a blog post of his own.
In Microsoft's vision, it's the PC plus Bing, Windows Live, Windows phones, Office 365, Xbox, Skype, and more.

"Our software lights up Windows PCs, Windows Phones, and Xbox-connected entertainment systems, and a whole raft of other devices with embedded processors from gasoline pumps to ATMs to the latest soda vending machines, to name just a few," Shaw writes. "In some cases we build our own hardware (Xbox, Kinect), while in most other cases we work with hardware partners on PCs, phones and other devices to ensure a great end-to-end experience that optimizes the combination of hardware and software."
Shaw notes that the Apple II, Commodore PET, and other devices preceded the first IBM 5150 PC running MS-DOS but says it was the IBM and Microsoft partnership that "was a defining moment for our industry" and fulfilled "the dream of a PC on every desk and in every home."
The first IBM PC even predates the Macintosh and Windows, which launched in 1984 and 1985, respectively. Shaw says he still owns his first computer, the IBM Personal Portable booting MS-DOS version 5.1.
