Is your next computer a tablet

.

As the desktop computers disappear from the retail stores the tablets are taking over. Most people in the older age group will worry about being able to manipulate and see these newer touch screen devices. It has to be remembered that the important specification is the "Dots per inch" (dpi) value. This is a characteristic of the screen resolution and the diagonal dimensions of the screen. The higher the dpi value the clearer the picture. A typical high resolution desktop screen has only 100 dpi compared to a 7" tablet having over 300 dpi. That is 3 times clearer and brighter. The other factor going for tablets is the "Pinch to zoom" feature making it easy to read small print with one movement. Security is at a much higher level for tablets except for the Windows 8 pro tablet which uses the standard windows 8 OS and needs the normal virus checkers and updates.
