It's becoming more prevalent that computer manufacturers, along with hand held device companies, are turning to touch screen technology. The Apple iPhone is one prime example, and now HP is offering their TouchSmart PC (Flash warning). Does anyone really need such a thing? What's wrong with the keyboard and mouse? I can see touch-screen technology used at kiosks in stores or museums, but I'm not exactly sure I understand the appeal of it at home. At the very least, I don't want fingerprints all over my screen (which is exactly what I'd get). Does anyone have any idea who would want such a setup? Maybe the target market is older people who aren't familiar with the mouse and keyboard paradigm.
