> a significant part of the world is already running lower powered devices

but you cannot consider this in isolation.

The developed markets have vastly higher spending consumers, which means companies cater to those higher spending customers proportionately more (as profits demand it). Therefore, the implication is that lower spending markets gets less investment and less catered to; after all, R&D spending is still a limiting factor.

If the entirety of the market is running on lower powered devices, then it would get catered for - because there'd be no (or not enough) customers with high powered devices to profit off.
