1) The article itself notes that Xaiomi's flagship phone is already facing declining sales in China (Apple is still increasing sales there, so who should be worried again?).
2) It's running Android - the closest equivalent product is the Samsung Galaxy S5, surely the headline should be warning Samsung, not Apple (Apple has a nice competitive moat by having their own OS / AppStore ecosystem).
3) Speaking of ecosystems, does this thing have Google Play (I looked on their site, but couldn't get a clear answer - no Google app logos though...)? If not, it's really going to struggle in Western markets.
