We speculate because its fun. But its not like we're pulling ideas out of the sky. Bits and pieces have been given to us, for example, iPhones now have fingerprint sensors. Its unlikely that all they'll ever do is unlock our phones. We also know of general problem spaces like mobile payments, or health/fitness tracking. Tim Cook himself said wearables are an interesting space and that he wears a Nike fuelband, thats pretty much a signal that they're working on a wrist device. We also know about their high profile hires of people who worked on health devices. Ultimately, we entertain these assumptions because its fun and potentially profitable for us.
