第10题
Apple’s new computers are much faster and more powerful than its earlier models. The improved Mackintosh is able to run programs that previously were impossible to run on an Apple PC, including IBM-compatible (兼容的) programs. This compatibility feature illustrates computer manufactures’ new attitude of giving customers the features they want. Making Apple computers capable of running IBM software is Apple’s effort at making the Mackintosh compatible with IBM computers and thus more popular in the office, where Apple hopes to increase sales. Users of the new Apple can also add accessories (附件) to make their machines specialize in specific uses, such as engineering and writing.
The new computers represent a big improvement over past models, but they also cost much more. Company officials do not think the higher price will slow down buyers who want to step up to a more powerful computer. Apple wants to stay in the high-price end of the personal computer market to finance research for even faster, more sophisticated computers.
Even though Apple and IBM are major competitors, both companies realize that their competitor’s computers have certain features that their own models do not. The Apple line has always been popular for its sophisticated color graphics (图形), whereas the IBM machines have always been favored in offices. In the future, there will probably be more compatibility between the two companies’ products, which no doubt will require that both Apple and IBM change marketing strategies.
