Упражнение 55. Прочтите и переведите следующие микротексты, содержащие модальные глаголы.

Before you buy a laptop

As a mobile office worker you want a laptop that you can take with you easily. You need to be able to connect to the Internet and company networks in a variety of methods. The next important criteria when you buy a laptop are size and weight. The best choices for mobile office workers are thin & light laptops. Laptops meant (предназначенные) to replace desktop systems may be too heavy to carry for long periods of time but can provide features valuable to mobile professionals. Mobile office workers must accept that their laptop will be a prime target for theft. Making the decision for a laptop that includes security options can save you money and grief. As with all technology, mobile office technology is constantly changing and improving. If your laptop can't be upgraded it can become a hindrance (помеха) rather than an effective tool. And sometime you could be left without an efficient means of connecting to your company network or the Internet.
