Are there enough of them to make such a product viable? Remember, you're up against products produced in such volume they become their own commodities. iPhones may cost some $650 full price, but is there seriously any way a modular phone could really compete without deep optimization to such a massive supply chain? anyone willing to pay $1500+ for an underpowered phone just because it's modular? These are not rhetorical questions. All that said, methinks here IS a market for a very well made dumb phone. Anyone carrying an iPad everywhere doesn't need an equal but smaller iPhone, just something like an iPhone nano (makes calls, great ecosystem integration, refined UI, and nothing else).
