And Windows Phone/mobile/whatever the f their calling it is pretty well optimized to run on lesser hardware. That's not the problem. Spinedoc laid out the problem perfectly...
Yeah, can do that on Blackberry devices and the Amazon Fire Phone as well. General consumers all love having to side load apps. Remind us how well those devices are doing.
Without native Google apps/services, Tizen would be as dead in the water.
I think Samsung genuinely would love to replicate Apple's top to bottom control of hardware and software using their own OS but it would be a huge mistake, IMO. They don't have the dedicated, loyal customer base that Apple has to pull that off.
Samsung isn't going anywhere...they are still making very good devices and have the hardware infrastructure to keep making mobile devices with better hardware than just about anyone. They'll be on top of the Android OEM pile for years to come...they just can't expect to achieve the same level of success because as Jamezr pointed out, the Android space is getting incredibly competitive and right now, it's coming down to price. When Motorola, OnePlus, Asus and others are starting to offer top level devices at huge discounts to traditional flagships, Samsung's bottom line is going to suffer.
