The opening paragraph:

    > Xiaomi is the Chinese tech giant. Their phones compete with iPhones.

To the first: I say, "Hmm... maaaaybe. More like they are a large consumer goods company. Many of their goods are very low value." No one doing professional stock analysis on Wall Street would put Xiaomi in the same category as Huawei (which has a frighteningly large and effective R&D division for telco/networking kit).

To the second: I summon my inner Aussie: "Yeah, nah." I think only peak Google Pixel or Samsung Galaxy phones are the only two that can possibly challenge iPhones. The rest are poseurs.
