If your writing for the market it makes little sense to write for
anything other than VGA (velcro graphics). You almost can't do
anything without one. I reluctantly switched from EGA since most of
the apps I run are in text modes. I only get testy when writers are
trying to sell programs the require 6 bizillion hertz pentium with
64 mega gigs of memory and enough hard drive for greyhound. Most
people can't afford an upgrade every 10 days or so. :)
It's great that computers of today are so fast and have so much storage.
It saddens me that it also lends to some very sloppy programming in
the terms of size and speed. Whatever happened to tight fast code?
