Ok, time to clear up an obvious and totally incorrect assumption, higher
resolution does not mean small fonts that are hard to read. It means
that you have clearer, sharper fonts at the dpi you find comfortable
reading at. In other words a VGA screen is just better, better for
people with good eyesight and _much_ better for people with poor
eyesight. I'd always go for a higher resolution every time.
Now some of you people out there may run windows on your desktop and
only being able to reasonably change dpi between two settings (maybe
this is different in Vista) means that a high resolution often does mean
small fonts on the screen, some can't go to 120 dpi because maybe the
apps they use don't support (yes that used to be quite common). On Linux
this is not a problem as dpi is entirely variable and changing it
doesn't break applications. In that case the dpi is a simple personal
preference and on higher res screens everything is sharper and easier to
to read, reducing eye strain and so on.
For a small device where we will be trying to read things that are
already small due to physical screen size a high res is a must to make
that as comfortable as possible. VGA will produce a much better user
experience than QVGA and be a lot easier on everyone's eyes.
To summarise we have 3 orthogonal concerns:
1. Screen dimensions - fixed by manufacturer, relates to device target users
2. Screen resolution - fixed by manufacturer, higher is better for all
tasks that require screen reading, for movies it really doesn't matter
3. DPI - user specified to reach a compromise between readability and
effective use of screen real estate.
Any, that's my take on things, I vote VGA ;-)
