They keep getting worse, too. I loved my Galaxy Relay. I bought a Moto Z because someone was making a keyboard backplate for it... And they killed off the project a few months later.

The only thing worse than the on screen keyboard is Blackberry's physical keyboard. Give me some kind of slider.

My first Android phone was Motorola Dext, second one was HTC Desire Z, which I held on to for a long time. By the time I had to replace it, there were no slide-out keyboard phones any more.
Then some time later F(x)tek X1 Pro was released. Looked like a perfect phone for me, but was too expensive, so I did not get it. But now that it's time is over as well, I look at the reviews and see that I did not miss much.
So now I am sadly on a glassy rectangle like everyone else, but I do carry a collapsable bluetooth keyboard around with me sometimes, so that I can still type some longer text in a proper way.

Also, I solved my no-headphone-jack issue by getting USB-C headphones. And there are USB-C to 3.5 jack adapters if you need to connect existing headphones or other equipment. So I don't really get how this "I miss a hole" is everywhere and lasts for so long.
