There’s a reason the first thing in Windows 7 that Microsoft chose to show publicly was its support for touch input.
That built-in ability to use two fingers to rotate, scroll, and zoom offers tangible proof that the operating system is different from its predecessor, not to mention being something not found on a Mac.
However, many say that comparatively few Windows 7 PC owners will actually be reaching out to touch their screen. That’s because, to use one’s fingers in such a manner requires a screen that can support the technology–something that often adds $100 or more to the cost of a PC.
As a result, many expect touch-capable computers to be just a tiny fraction of the market for desktop and notebook computers, even after Windows 7 arrives on store shelves on October 22.
