A touch screen for POS would be an exception to the general rule because of
the level of actual control, but certainly you shouldn't if you as stylist
are targeting normal screen media where you can't be aware of the user's
requirements or environmental characteristics. That's what's wrong with
today's web and the sizing in px that overwhelms it. The ultimate size for
the web should be controlled by the user, and no more than once per
installation, by declaring a preferred/base text size. Everything else should
be relative to that, in order that the maximum number of users can be happy,
and web objects be accessibly and usably sized for all sighted users of true
personal computers. That base/reference size can only be determined by the
user. If the actual size of a pt as a non-physical unit for screen media
turns out to be readily controllable by the user, then I'm in favor of its
implementation. It should then be easy for those familiar with sizing in pt
via print media expertise to transfer that knowledge to screen media styling
that adapts to sizes that work for users just as well as em-based sizing.
