One should be at the bottom one at the top. I understand space on the phone is a premium but a second port would make the phone so much more usable. Wired headphones, flash drives, camera modules, speaker modules, keyboards, even connection to a TV, all could be used while charging. It’s a shame it’s not a thing, USB is extremely versatile port, but you only get one and it’s used for charging half of the time. (I am aware dongles exist)
Many countries not so well off like us in the West do not have the luxury to have a smartphone and a computer. So options with 2 USB ports would be interesting. The bastardisation of the smartphone is a disgrace.
What exactly is getting bastardized? Phones never had 2 USB ports. And there are still new phones with headphone jack (Zenphone 10 comes to my mind). Yes, many brands dropped it, but it’s not a conspiracy (or at lest doesn’t have to be), it’s just basic economics.
What I call bastardisation is the many steps stopping us from using our phone as general computing platforms. Our phones have no reason to be confined by software locks like locked bootloaders, root login, etc.
As for the lack of 2 USB ports, it pictures that phones where never thought as general purpose computers. Maybe two ports is not the way to go but the lack of an interface which can act as a display output and a USB connection like what we have now with Thunderbolt on the desktop is a shame. The inability to turn my phone, which is more powerful than my current laptop, into a normal computer unencumbered by software and hardware restrictions is a shame.
The path taken by Pinephones and their Linux ecosystems is a step in the right direction. It shows that smartphone companies can do better.
As you said, it’s basic economics, it’s more profitable for them if we buy a new phone every two years, so they lock us out of our properties with software and hardware restrictions because they can.
