The missed the atrona which ran cpm and msdos both and was
much smaller than the compaq they had in the article.
I think that some of the choices in this article may be skewed by
the fact that journalists have their own peculiar needs in portables.
I think they use such units as will support the text preparation and
transmission functions they need, and don't tend to require a full
functionality of a desktop as can be obtained today.
I have seen articles as recently as in the last couple of years of using
small tandy portables to enter stories on and transmit them by
modem being used by some reporters. I would guess it is sort of
like the same as figuring you are comfortable with your underwood,
and not going to be forced to change.
