You can't be serious. Samsung has a far better supply chain than Apple. In fact, Samsung IS PART of Apple's supply chain.

But Samsung is not the kind of company that would take risks with a market and they'd rather ride on the coattails of those who are willing to push the innovation into the hands of the consumers, and it's not something specific to their mobile division, it's the same for their digital cameras, home appliances.. I've seen during the history of photography most of the big names doing something that may have impacted the market, while Samsung is just saying "hey, me-too!" months laters.
