One of the first things marketed with the new Windows 7 is its ability to support touch input. Using two fingers, you will be able to scroll, zoom and rotate web pages and documents. This is unheard of on Macs and is not available through earlier versions of Windows.
Unfortunately, reports suggest that this may not be a technology that everyday pc users will be taking advantage of. One of the biggest obstacles is that this technology requires a touch screen monitor which will add at least $100 to the price, something many will not opt for. It is believed that this feature of Windows 7 will not be mainstream even though it is being touted as one of the best reasons for the upgrade.
