  Portable music devices, lap tops, home computers, video game consoles and cell phones are just a few of the electronics that now use touch screens. Touch screens appear modern, sleek and convenient, but they have several problems as well. Weigh both the pros and cons before deciding if a touch screen is right for you.
  
  

Precision

• Depending on the size of the monitor, you may have trouble being precise on a touch screen. Touch screens are made for typical hand and finger sizes, and those with larger fingers may experience frustrating inaccuracy when navigating a touch screen. The arrow pointer on a monitor connected to a mouse ensures that you click on one thing at a time.
  
  

Cleanliness

• Fingers naturally accumulate oil and dirt. There is no way to avoid soiling a touch screen with the oil and dirt from your fingers, as you must physically touch the screen to operate the computer. When you dirty a keyboard or mouse, you do not affect the screen. When you dirty a touch screen, you can distort and ruin the surface which transmits the picture.
  
  

Obscurity

• While operating a touch screen, it is inevitable that you will obscure part of the screen, as your navigating hand blocks text and pictures. While navigating a monitor with a keyboard or pointer arrow, you can fully see the results of your choices displayed on the screen.
