It used to be common knowledge that touch screens were something that were in the far off, distant future of technology. However, the veritable explosion of touch screen technology over the past five years has led to that future being rewritten. Though LCD touch screen monitors were once very expensive, they are now very commonly available and at a fraction of the cost you'd expect to pay if you look in the right place. Look for LCD touch screen monitors that come integrated with a hard drive. These monitor/hard drive combinations often end up saving you a lot of money, and they serve more than one purpose.
