An improvement over Pi 500 in many ways, but adding keys to the right of heavily-used (r) Shift / Enter / Backspace would make it much harder to find these keys without looking at the keyboard.

The previous version also had half-height arrows that had some negative space ("not keys") above them, and so it was easier to position the fingers over the arrows just by feel; this one makes it harder.

I'd hope the next generation returns to the previous keyboard layout (which was almost perfect for me.)
