It's no secret why Aetna would consider handing out Apple Watches like so much candy. As one of the tipsters says, Aetna hopes that this would encourage customers to lead a healthier life.

Apple, meanwhile, might see this as part of its growing plans to become a mainstay in digital health. If it's willing to take a financial hit, an agreement could score millions of new Apple Watch customers (some of whom might become repeat customers) and cement the Watch's reputation as a fitness tool.
