It certainly made me laugh though when I saw that the keyboard was thicker than the phone... it makes perfect sense though when you realise there's a battery as well as the keyboard there though. It's nice how the pinephone seems to snap in as if it were a replacement back panel.
How does this charge (as I notice there's no picture of the right side)? Does it have any priority in which battery charges first? (i.e charge the pinephone battery before the keyboard battery) Is there any room for future expansion... i.e. can the lora backplate be integrated into that as well? wireless charging?
So you charge it via the USB-C port on the keyboard. That will charge both the keyboard battery and the PinePhone itself. Not sure what the chagrining priority is (I'll ask), but I think that the charging goes: keyboard battery -> PinePhone battery.
It is my understanding that officially there isn't any room for expansion inside, same pins are used for Wireless charging, fingerprint scanner and keyboard - not sure if you could hack up something stackable. I guess we'll find out in the next few months

As is, I think the layout that has been decided on is a good compromise.

Looking good, Just wondering about charging, is the charging speed from the keyboard to the phone, any different than using the usb-c port in the phone?
If I plug the usb-c port in the keyboard will it charge faster than the usb-c port on the phone, will it charge the same, or slower because the charge has to go through the pins when getting to the actual phone?
Does the speed depend on what battery it's charging? If I'm charging the keyboard 's battery because the pinephones battery is full, would the keyboard charge faster if I plugged it in using the keyboard slot, and the same if I'm charging the pinephone's battery rather than the keyboard, would it charge quicker using the pinephone slot, or the keyboard slot, or is it all virtually the same?
Thank you!

Will you support japanese and korean keyboards?

This looks great! Can't wait to pick one up.

That's what I thought... but if the keyboard works over I2C, that is a multi-device bus, so you can have multiple devices all on the one bus
Making an-all-one quite possible... hopefully someone accepts the challenge!

That would consume most of the available power from a typical USB-PD charger (assuming the charging circuit will use 5V). There would be some 2.5W left for the use by the phone itself, which is so so for use but not for charging.

The rest is anyone's guess at this point. Anyway, I don't think keyboard charging circuitry can control when the power gets to the phone all by itself. It would be best for usability if both charging controllers were controlled by the SoC somehow. Otherwise there will be a plenty of weird edge cases.

I would prefer the aesthetic of blank keycaps. Maybe with the exception of the pine key.

The backslash and pipe for me are on the right side, one row above and to the right of the semi-colon/colon key... but this is because I have the ANSI 101/104 layout keyboard, which is standard for this part of the world. You probably have the 102/105 layout keyboard, which puts the backslash and pipe on the bottom left, as well as some other funky layout changes. i.e. as highlighted with the red keys on https://en.wikipedia.org/wiki/Keyboard_layout#/media/File:Physical_keyboard_layouts_comparison_ANSI_ISO_KS_ABNT_JIS.png
At the end of the day... as I'm sure has been mentioned somewhere, they are sticking with the ISO layout for now (presumably because there's more customers who want ISO than ANSI), and will consider ANSI layout if the turnover for the keyboard is sufficient.

What it could control is which charges first, just like my Asus Eee Pad used to. When you plugged the charge lead into the keyboard, and the tablet was docked, it would charge the tablet battery first, and then the keyboard battery... thus if you unclipped it from the keyboard, the tablet battery would have had as much of a charge as it could get.
I agree with the rest though... but actually suspect that both chargers will be in parallel, so will need a beefy charger to charge at maximum amperage for each, or the keyboard charge rate limited.

Have to say @Luke this is looking great
Brilliant vision
No suggestions or extra requests from me
Can't wait
Lots of use case scenarios
