Monday night on Apple’s earnings call, CEO Tim Cook talked about new product categories in his opening remarks. While this isn’t new news, his further explanation hinted at what Apple could be cooking up next in Cupertino. ”In terms of new product categories, specifically if you look at the skills that Apple has from hardware, software and services and at incredible app ecosystems, these set of things are very, very unique,” Cook said on the call. “I think no one has a set of skills like us and we obviously believe that we can use our skills in building other great products that are in categories that represent areas where we do not participate today. So we’re pretty confident about that.”
