I used to buy a new computer every two years. My home got three to four computers. I am still using these computers. For some of very old computers, I use them as a file server. I have not put them into rubbish bin. Some of my friends put their computers into rubbish bin. Actually, many old computers are still useful. They may be not good to play games. But they are still good to do word process. I have hear there are some version of Linux aims to run in low performance computer. Please, Please, Please don't treat your old computer as a piece of rubbish.
