In the past, experts made wrong predictions. In 1977, the president of a computer company said, "There is no reason anyone is going to want a computer in their home." Today, most homes have computers. Futurologists predict that in the next few years, we will have electronic books, domestic robots and solar‑powered cars. The Earth's climate is going to change, and this will affect people's lives. Some products on the market are amazing. For example, the Fujiko micro camera is smaller than a credit card. It has an automatic focus and flash, so it's very easy to use. Another invention is the Segway Human Transporter, which is a convenient and pollution‑free way to travel.
