Grabbed a Nexus 5 myself, because hey, it's pretty hard to beat for $300 and also because of it's tight integration with Google service, with which I myself am tightly integrated.

But, for my mother? She couldn't give a damn less, which is where I think a lot of these smaller manufacturer's will succeed. I actually quite like the idea of a simplified/dumbed-down Android experience that Xiaomi is offering and would seriously consider it for my mother and less tech inclined friends/relatives.
