I think we can make a decision for the blind people or deaf and dumb. We can produce the computer which do not have monitor and graphic card for blind people because the blind people can not see the screen and only can control by voice command and keyboard. The computer should add a microphone into the computer so that they do not need to spend more more money buying the common computers as others. It may save some money. Also the similar decision is to remove sound card and microphone inside the computer. I think this is good to disables.
And although nowadays the information technology is more advanced, and the computer become more and more portable or they become more usable, they have more functions, they run faster and faster and they only cost not very much money, they are cheap. Company also need to buy some single computers because if the computers are too latest, the workers may use them play computer games, chat online, watch the movie and listen to music so that they can not concentrate on working. The workers only need to do working with excel, word, search the internet, make accounts. So the computers with single components and old design components are much cheaper than latest computers. I think this idea is necessary to the company.
