There is no point in continuing arguing about the screen size. It is set in stone and the choice has been made based on (1) actual constraints that can't just be ignored (parts availability*) and (2) design decisions (as in engineering, not aesthetics). It's not just a blind random choice.

In all honesty, I would buy this device even if Chen came up tomorrow announcing that the only way to build a keypad in 2017 is to source blinking RGB keys.

Let's move on and be supportive. The device will be as good as it gets, or won't be at all, and even with some minor frustrations depending on people's preferences, it will still be far better to people who want an open bootloader with a keyboard and a choice of OS than anything any other manufacturer has to offer (or impose). It will in fact be the only device to offer that. There's no match.

* This tiny Jelly device got $1.25M and there were enough resources to build working prototypes before the campaign, plus it does not try to reinvent the wheel, it's just a small Android phone. Livermorium plays another move here, and this seems to be something that may be more interesting to people in this thread.
