Just the Touch of a Screen

IF you have ever used a smartphone, then you know about using your fingers to navigate the screens. Whether watching the news anchors use them on TV news or noticing that teachers are using touch displays in their classrooms, it seems that replacing the computer mouse in this way is not only stylish, but it is simple and convenient. With touch screen technology, you can do anything from ordering postage at the local post office, to making choices on a computer screen at the local museum, to searching the internet.
