I used to agree, but the point I made in GP is that the touchscreen front and center could be a requirement, with what to do with one being open to local market interpretation.

IF that's the case, and that's one big if, debating touchscreen vs buttons might not be meaningful, because touchscreen MIGHT be a requirement that cannot be removed. With un-eliminable touchscreen, buttons becomes just added cost, rather than being a resilt of cost calculations between all-touch vs all-buttons.
