You can't replace the feel of a book. All this is true. Computers are unfriendly beasts and it is unlikely that the printed book will ever disappear but ebooks are becoming increasingly attractive. We are all now aware that the typewriter has largely disappeared to be replaced by the word processor. This computer program allows words and graphics to be visually displayed on a computer screen.
Word processors enable changes to be made quickly and easily to the design and layout of the page.
If we need the words to be larger, or bolder, or in a different font design - these can changes can easily be made. Computer VDU screens continue to see many improvements. Flickering green text in one standard format has been replaced by coloured displays, with sophisticated layout capabilities allowing colour, graphics, even sound and video to be incorporated to allow multi-media display. The screens are easier to read, with rapid refresh rates, meaning they are less tiring to the eyes and many unwanted emissions have been removed. Font designs have also improved, with text fonts now specifically designed to be read only from the screen.
