It's a shame there isn't the kind of competition in the US when it comes to mobile phones as there is in China. Many HN users would likely never buy a Chinese OEM device, but if you look at the variety of devices offered by Chinese brands, they're trying all sorts of approaches. Kind of like their EV market. Meanwhile, your choices in the US are Apple, Samsung, Motorola, Google, and that's pretty much it. I wouldn't say there's a ton of innovation between them...kind of like the large US automakers.

Depends on if it starts to get a crease after using it a while. I tend to assume that this is why Apple chose not to adopt folding screens as quickly as Android phones did.

I mean that is the business. These companies are in the business of ordering parts from components vendors and leasing floor space to assemble them after all. Folding screen is probably something you can order from many companies in shenzen at scale right now (or whichever chinese city is the "cell phone screen" hub, might not be shenzen).

Just like the first iPod and iPhone.
