The only problem is nobody knows how to make a useful keyboard that fits in my pocket. I hate touch screens in general, but a phone in my pocket is useful in many situations where I wouldn't bring a keyboard.
There are lots of folding keyboards available. The problem is that they are made for using on a table. Phone doesn't work well on table.
It should be possible to make keyboard the size of a phone that can be used in the hands. The problem is how to hold it, maybe the iPhone magnets would make that possible. I think the main problem is that everyone is used to using touchscreen keyboard and wouldn't think to use keyboard.
I have an ancient Stowaway Bluetooth keyboard, one of the best folding keyboards made, and I have stopped bringing it along. I found that screen keyboard is fine for small amount of typing. And if I need to do actual work, then laptop or tablet is needed.
I got to play with an HP Veer circa 2011, a phone the size of a credit card, specifically to try out the keyboard (specifically, I remember visiting this website).
It was a far better typing experience than the iPhone SE ever was. Tactile feedback was solid, shockingly so.
But could you swipe entire multi-syllable words in a single fluid gesture, and have it recognise what you meant? Sure, if I were pressing keys one by one, that tactile feedback would be great. But that's hardly ever how I "type" on my phone.
The Veer's keyboard really worked well. The small screen was problematic for many sites, sure, and not having a good browser hurt it a lot (and especially the bugs, like reloading a webpage on first touch after inactivity, which means reloading it immediately after a long load time...). But the keyboard makes me want to use it again.
The BlackBerry KEY2 was great. I was hoping a KEY3 would come out but haven't heard any updates. I recently tried Unihertz and F(x)tec phones but they were both terrible quality (WiFi dropping out and callers intermittently couldn't hear me on a phone call, respectively). For now, I've given up on keyboard phones. Coincidentally, I just bought a Motorola Edge 5G. There wasn't much logic to it: I wanted to be different/hipster, so I didn't just want a Samsung or Pixel. It has been good. The price was good for the quality.
The moto backflip, despite being a flop, actually had a really cool idea on how to handle that. So did the blackberry priv. For whatever reason, the market just didn't want it. I guess the market has skinnier thumbs than me, because typing on even a 6.6" touchscreen feels like typing with boxing gloves on.
