I would also like to have a better screen on the iPhone! If you open a

It would still be approx. 30% better than a QVGA 2'8...

I have now thought a lot about why they have chossen 320x480.
Most probably, they have spent a lot of money and useability research
to find the
**best compromise** between number of pixels, dpi, speed, readibility,
density and cost.
* QVGA is worse (!) than the best compromise (as benchmarked by the
* VGA is better to use - which has its price.
So how should one decide between two contradicting requirements?
In the view of openness and unknown future applications, I would pay
to go beyond the best compromise. Even if it needs a more expensive
to get the speed.
