This is the thread's initial revision.
I just have two comments. It seems to me that there were a number of laptops available in the mid-1980s. I myself bought one called "Micron". Is the Toshipa laptop then the "world's first", or the first in Japan? If not the first, in what specific ways is it innovative enough to warrant the milestone honor? My second comment- The pdf endorement letter by a Toshiba executive is confusing- it refers to "the first Japanese-language computer" of the 1970s, NOT the laptop. Was the wrong letter put in by mistake?
