It looks like they’re combining two options into one, like instead of having you choose “optional keyboard Y/N” and then “keyboard language”, you just choose them both at once, like “optional keyboard and if so, what language?”

From another post about this yesterday, I found in the specifications section of their website, a “what’s in the box”: No mention of a keyboard. So the base model has no keyboard. So ya, choosing the layout is also opting for the keyboard, and, adding an extra ~$100 to the price.

Do you think it is overpriced?

Given its capabilities and the fact that you can buy used MS notebook/360 device for such a price? Of course.
