Some of us are more environmentally conscious than others. Most tend to want to help the environment, but admit they could do more. Corporations are the same way. Check out The Green Electronics Guide. This guide from Greenpeace lists companies and their records for environmental responsibility. We commend Greenpeace for its efforts to get companies to remove toxic chemicals from their components.
When it is time to dispose of your old electronics, if you cannot find someone to use them, research takeback programs. Dell, for example, will offer you a recycling kit with every computer purchased to allow you to rid yourself of an old one. If this fails, there is always donation. Allow your old tech to be someone else new tech.
