If you insist on a thorough demonstration of the material you are considering buying, you can evaluate it in terms of its ease of use and the usefulness of its analysis.
If you're thinking of buying a new software package for a computer you already have, ask to try it out first. Some software distributors in the public sector will give you a trial period to make sure the program is satisfactory and runs on your equipment. Or you may be able to obtain a demonstration disk. At least, try out new programs with the same microprocessor, printer, and screen you use to make sure they will work on your equipment.
It's useful to have software evaluated by a reputable source—for example your local county Extension agent, State Extension specialist, or a neighbor who has had experience.
"Let the buyer beware" is a good motto to remember as you shop around for a computer system.
Getting Comfortable with Computers
If you can use a typewriter, you can use a computer. Most agricultural program's do not require particular math or technical skills, just a knowledge of your farming operation and the ability to think in a logical, orderly way. Most new programs are user friendly; they ask you questions in plain English, and you type the answer on the keyboard.
A good way to feel comfortable with computers is to try one out at your local computer store, or at fairs, conferences, or workshops at universities.
