Steve Jobs hated the idea of a stylus and said during the first iPhone announcement that we’re born with the best tracking devices; ten of them which happen to be our fingers. Apple has taken several decisions differently ever since the demise of Jobs and according to a new rumor, an iPhone that provides support for an Apple Pencil could be seen as early as 2019.

This new rumor comes from The Investor and it details that Apple is mulling the idea of an Apple Pencil that is strictly designed for the 2019 iPhone, meaning that the stylus could be a lot smaller and thinner than the accessory that is used with the iPad Pro series. It states that this pen accessory is expected to adopt a supercapacitor stylus type which will result in cost benefits.
