I suspect you may not represent the majority you *think* you do.  I know
a great many people who run their systems (with LCD display hardware) at
under resolution because they do not want a large screen area with tiny
elements.  The scaling hardware in the LCD gives them the "resolution
independence" they need, but we can (and should) do so much better!
