There has been a lot of changes in the past two decades or so since the first laptop computers appeared. From many years there has been a revolution in the field of laptop manufacturing. We have come across lot of changes in their hardware components and software. The processor speed is in gigabytes now. But we cannot make out more changes in its hardware components. As we can observe that the laptops that are seen in the past and that we see now have many physical features same as before. Now it seems to be changing from traditional design of opening display lid and the mechanical key board to more exciting features. According to Mike Trainor(INTEL Corp.) these types of laptops are likely to be in the market before 2015.In early 1990s, concept of integrated pointing device, webcam and speakers where some of the ideas which are integrated part of the device now. Today’s concept laptops are really amazing. Several concept laptops rely on touch sensitive screens that act as the system's keyboard and mouse and go beyond today's multi touch technology. Imagine being able to slide your finger across the screen to immediately shut off the display and keep what you were working on confidential, and you get an idea of its potential.
The display and the keyboards are similar to the slider phones available now. The pair of super bright organic LED panels slide into place next to each other, with the lower panel acting as keyboard or scribble pad.The whole thing is only three quarters of an inch thick. Together, the 11in. screens will yield about 16 inches of usable workspace, so the system has the dimensions and weight of a thin and light system but the screen of a larger one.
In another type, instead of a display and a mechanical keyboard, the device has two touch sensitive displays. The upper screen is primarily for viewing applications, and the lower screen is for the activities like typing, drawing and jotting notes. It can also lie flat for a large expanse of working space.According to designer, this notebook changes personality depending on how it's held. Opened all the way, it's a sketch pad. Fold it half open and rotate it 90 degrees, and it's an eBook.By emulating a musical keyboard on the lower half, when it's flat on a table, it can be a go anywhere piano.Beyond all these features these type of laptop is power saving since it uses led in it. This will consume much lesser power when compare to LCD display that is used today.
These laptops use the alternative power source, by their own energy source like methyl alcohol or natural gas will make their batteries run longer and be more independent from the electricity.
