In the computer industry, the equivalent of a compact car is a sub-$600
computer. The technology in these computers is usually a year or two old

about your computer usage, you’re more likely to buy the right computer
and not have to purchase expensive upgrades for it later. Figure 2-9 offers
some guidelines to help you evaluate how your plan for using a computer
