Just because it is so simple mathematically, the Plate Carree (or
equi-rectangular) projection is no less of a projection than
others. Like <i>all </i>projections, it has its distortions and
yet it preserves some geometrics. It is in the class known as
"equidistant" projections. In this particular case, scale is
preserved along the equator <i>and</i> at all points on the map
in a direction perpendicular to the equator. (Pretty impressive
for something so simple, eh?)<br>

is nothing to stop you however from treating lat/long as
rectangular coordinates and using that as a "projection". The
projection figure is Plate Carree and <i>this has no redeeming
cartographic features as a projection</i>.</blockquote>
