Way to go, modern phone screens are not too bad..I think a big reason I enjoy dumb ereaders is the lack of multitasking lol

Your kindle probably has a busted micro usb port (the cables too can stop working for data transfer), no idea if it's too difficult to solder a new one.. I would try cleaning it up really well first

No but you can jailbreak them, and their OS is linux-based; unfortunately if it's a new Kindle or newish with an up to date firmware, you might have to wait for someone to release a new jb method. With a jb you can install Koreader (which alone can do everything useful), but also people (mobileread forums) have compiled a working Python library and a terminal with bash..mostly useful to show off :) you can run neofetch

If you're like me and need Koreader (has impeccable pdf reflow and stardict support), a Kobo is way easier, and you don't have to wait

It's a powerful program but not a complete OS replacement

Yes exactly! On Kindles to install that app we need a jailbreak (and the procedure will depend on device and firmware version, since we are trying to circumvent Amazon limits), most of the OS stays the same and you can still use the normal "reader" app.

Of course if you are already satisfied by the normal reader all you need to do to gain more freedom is managing your books with Calibre on a computer, it'll take care of converting to kindle format if you put an epub in it, and send it to device, with just one click. My dad does this after I showed him once or twice and he's not techy at all.

The're right, another thing you notice in a dry house (like Swiss homes in winter pounding crazy heating) is that you can get even painful (to the hand) mini electric shocks just walking around with slippers/crocs and then touching the metal kitchen vent, chargers..unless you ground yourself once in a while. Never happens in a humid climate/house.

I think they're the same thing as cable holders/organizers
