I mean, I don't expect to see a nice full color photo of hawaii on the
a2 screen.
But I'd like to be able to draw a graph or some "complex" display of
let's say a wave with numbers and text and colors, for example, with a
decent resolution.
One is vectors/shapes/text the other is a bitmap.
You don't usually need to save this kind of drawings as a bitmap, rather
you redraw it from primitives.
In this sense, it makes sense.
As for the bitmaps, it doesn't.

Trust me, when people are talking VGA, they are talking about
*picture*, not just *diagrams*.

And, as I mentioned, even the diagrams you describe will take
several times as long to draw as it takes to draw them (in
lower resolution and limited colors) on the Apple II screen.
