If you're shopping for a new computer, consider a refurbished model to save the environment and a few bucks, too. Many major computer manufacturers often receive returns on computers due to minor technical glitches. Apple, for example, repairs these computers and puts them through a rigorous process to restore them to good as new; bugs are fixed, while cords and cables are replaced. Everything's completely tested. It also comes with a one-year warranty. For some computers, savings can be up to 50 percent off the retail price.
