The company has sold 3. 27 million iPads since they entered t he market in April. Although it’s impossible to know with certainty how many seniors(老年人)are buying them, evidence suggests that it’s a hit with seniors.“The iPad’s intuitive interface(直观界面)makes it attractive to seniors around the world, ”says Takahiro Miura, a researcher at the University of Tokyo. “The iPad is a good tool for seniors because it’s very easy to use, ”he says. “Unlike the PC, it doesn't require former knowledge. ”James Cordwell, a researcher in London, says the iPad’s popularity with sen iors is helping Apple reach beyond its traditional base of young customers. “The world’s population, especially in developed markets, is getting older. It’s probably a market where Apple has least entered, ”Cordwell says. Senior users are“a key source of growth for them in the future”.Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes come with getting older. “Trying new things like that is a good mental exercise, ”he says.【语篇概述】文章要紧讲述了“苹果”传统的顾客是年轻人, 然而越来越多的老年人也开始喜爱用“苹果”。
