QVGA V/s VGA for GTA03 (was something about yummy CPU-GPU combos!)

Examples mentioned before:
* 24x80 console terminal for remote access of a server
* previewing a >300 kPix image (that isn't much resolution!) without  
scrolling/zooming panning
* monthly overview for a calendar where each day shows a reasonably  
useful content
* reading 12pt text (not only seeing that there are lines) of a web  
page designed for >=VGA without scrolling

One more observation: TV systems initially started with approx. 300  
lines (QVGA) and rapidly invented
the half-line interlacing system to come to 500-600 lines (more than  
VGA). So, the early TV from the 40ies were
not good enough but the 500-600 lines from the 50ies were good enough  
for 50 years. Now comes HDTV.
The use case was unchanged: viewing broadcast movies.

I think, generally everything *can* be done on a smaller resolution.  
The "solutions" are:
* scrolling
* flipping between pages
* reducing content

So, I am quite sure you will *not* find *any* application that is  
really *impossible* to use
on QVGA... As said before - you can *use* a Porsche as a vehicle if it  
has at least one
gear level. But would one buy it?
