That form factor is interesting, I had seen another like this before from somebody who had been travelling. Also interesting is that there seems to be demand for it in some countries and not others.
I think that's because, even hardcore smartphone with physical keyboard users have accustomed to touch screen, it's just few outliers and security conscious people are using the setup being discussed here.
That said, I see a resurgence of smartphones with physical keyboards and once people get used to them, they may seek better screen/keyboard/performance with a pocketable laptop but the GSM integration is a major limiter for many. It's not like people are going to throw away their smartphones for a portable computer anytime soon.
But the first time I saw an east asian laptop in this form factor was before modern smartphones took off. It was circa 2008 and it ran Vista. It might have been a few years old.
I have long been impressed at the small laptop form factors available in those countries. There are many fewer options for wide sale in the US for example. It would seem to me like further west there is less demand for something small.
