Play along - create a PinePhone keyboard
The mic is on the bottom next to the USB socket, so would work open or closed. It's the speaker/earpiece that would be a problem, and can't be sorted via the pogo pins. You'd probably also want buttons to accept/reject the call (easy - it's a keyboard after all), and a minimal display on the outside for caller info, time etc.

Alternatively you accept it'll need a bluetooth or wired headset for phone calls.

I don't like the half size keyboard, but if you're going to go down that route it's better to put it next to the hinge for improved grip and weight balance. i guess the key size and action won't allow conventional typing on a desk or table, so overbalancing when using the touchscreen may be more of a theoretical issue than the practical one it was with some of the Psion's competitors.

The hinges aren't the problem (or at least not the main one in this case).

I currently have a wallet style phone case that opens just like the keyboard shown in the mockup, it is not possible to use the phone with the case open unless you fold it all the way back so the phone is flat. If you have it open, as the keyboard will be, you'll either have the keyboard pressed into your forehead and obscuring your vision or it will be jabbing you in the neck (depends on which side you hold the phone). And whichever of those two options you choose you won't be able to hold the actual phone part flat against your ear.

It has a slide keyboard which is better than the Nokia N900 keyboard IMHO. At least it has all the symbols and modifiers I need for Linux shell scripts, Vim and Emacs. Any comments?

This is very much like the type of keyboard I would like to see (although why no function keys?).

I also find this kind of folding design a bit strange, especially because of the earpiece covered.
(However, it may have a hole at that location.)

If it may also have a small, probably OLED display and some buttons, it would still usable as a phone in folded position - it can be driven through the I2C line.
...or if it could be folded backwards, so fully opened with phone display facing to user.

However, I also feel an N900-like design (or the one above this message) would be much better anyway.
It may be a more complicated design though.
So far the best one for me is the keyboard of F(x)tec Pro1 - I use it as my daily driver.

Anyway, I would order a keyboard for my PinePhone to check the result if it is not too expensive.
I would be really happy if a well-designed keyboard would appear for PinePhone as it would be much more usable for terminal usage - also keyboard simplifies web browsing and other tasks.

Just checked this out, definitely looks like the best of both worlds. Pine64, go for this design!

Will we theoretically be able to design a keyboard with this component? I wish I could just get one I can insert onto a breadboard but these i2c devices seem to only be for PCB boards which means that I would need a development board for it. Once I got that I can test a circuit setup on the ATmega328PB and/or on a Raspberry Pi.

There is a kernel driver for the TCA8418 and I have used it with the Raspberry Pi. This chip should work just fine with the PinePhone. My dts overlays used for the raspi are at https://mozzwald.com/raspi/ and there is a spreadsheet there I used to help figure out my matrix for the dts.

I have a QFN24 breakout board available on OSH Park that you can put the TCA8418 on and use it with a breadboard.

I like it. I'm not too crazy about the wasted space above the keys, but I'm sure you have your reasons.

Would it be possible to move bigger versions of the dip switches into that space? It would be great if it were possible to turn modem, cameras and WiFi on and off without disassembling the phone.

I doubt, unless someone designs a mechanical arm which converts these movements. Smile
The basic idea of those switches was to disable parts in a hardware way.

You may put switches to that place but it will only able to do it using a software way, so practically it is not possible.

Too bad. Thank you for the information.
