Windows® 7 Touch Screen Laptops
Touch-screen notebooks are not a new thing, especially when it comes to smartphones and PDAs, however owing to disappointing hardware and the lack of OS support; they've remained a minute market niche for business notebooks and desktop systems until now. But, things look to brighten up with the introduction of the new Windows 7. It not only offers enhanced stability, better performance and a sharper appearance but it is also the foremost mainstream operating system that supports touch screens from the base. Windows 7 can run as a touch system at all levels of the OS. The result is smoother and more reliable response.
Pushed by the release of Windows 7 and new hardware, it is predicted that the number of touch notebooks sold could surge from today's 2 to 3 percent to a whopping high of 10 percent in 2015. To make more sense, they will be migrating from exclusively business systems to those that consumers buy as well. On the hardware side, the trick to adding touch is the digitizer, it is basically a translucent grid array that is located on top of a notebook's LCD display. Previously the initial resistive digitizers, which ran by deploying pressure to make two sheets of material touch, were not bankable and also needed too much pressure and only had the ability to handle a single input at a time.
In comparison, recent capacitive digitizers work when the user disrupts an electromagnetic field on the screen's surface with a finger or specialized stylus pen. It responds to the slightest of touches and can handle several inputs at once, which means one can use tougher programs, like those supported by Apple iPhone. Capacitive digitizers also make for more better handwriting visibility. Though character recognition is not close to perfect yet, it has gained enough momentum that most users can successfully enter Web addresses and also enlist words or short phrases. However, on the lapse side, touch comes with a price to pay. For systems with displays larger than those deliberated for a hand held, touch can add a couple of hundred dollars to the price of the computer. As touch-screen sales volumes rise, however, prices will fall.
