I am quite flattered by Coldcard's new direction; it certainly seems like a direct response to our 2021 Passport Founder's Edition.
They are even repeating the exact same mistake you did with triple A batteries, and that back design is really ugly in my oppinion.
I am almost certain we are going to see ColdCard Q2 after this, that will have similar batteries like you are using in current Passport device Smiley

One interesting thing we noticed is that it's about 4x6 inches, almost an inch thick (you can do the estimation yourself knowing the screen is 3.2 inches diagonal). I think many users will be surprised by the sheer size of the device. It's certainly not pocketable.
Did they release any dimensions for ColdCard Q1?
It's bet if they can release how it looks when someone holds it in hand, but in their defense I would have to say that most modern smartphones are far from being small and ''pocketable''.
I don't like this direction at all, but people like big screens (that crack easy).

Additionally, I think I found the QR scanner part they are using. This means the QR scanner is essentially a standalone black box computer running proprietary code. It also means that there will be no viewfinder on the Q1 screen: https://www.alibaba.com/product-detail/Embedded-1D-2D-Image-Barcode-Scanner_62478427468.html?spm=a2700.galleryofferlist.normal_offer.d_title.2e971000ZaPAEz&s=p
Admit that you came back in bitcointalk forum, after being triggered by release of new ColdCard Q1... I found your conflict really amuzing, can't wait for NVK to join the party soon and talk more about QR code scanner and device dimensions.
Speaking about code, Coldcard doens't care at all about being open source, so it' doesn't matter f they use propriety code.
In their defense again, secure element you are using in Passport is also not open source and it has security issues, that is why it was outdated by manufacturer Wink
