CNBC: If Apple CEO Tim Cook’s predictions are correct, some consumers will never buy a desktop computer. Tablets and smartphones could take over as the primary way some people access the Internet, according a recent interview with the chief exec. “We’re at the point where the iPad does what some people want to do with their PCs,” Cook said. The average consumer who only needs to check Facebook, send emails and watch streaming movies, for instance, only needs the computing power and the memory that a tablet provides.
