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

I agree with you that the VGA screen is very important for marketing the
Freerunner - other comparable smartphones dont have that feature and are
certainly no where near in terms of DPI. I am also assuming that OM wont
discontinue the GTA02 (Freerunner) when GTA03 comes out. So mass market
customers will have the choice of the VGA screen and at a cheaper price the
QVGA screeen+camera. It helps OM as they have two distinct phones available
on the same platform, consumers have choice and resellers have two models at
two different price points.

But one question that needs to be answered is - what is the cost saving of
using a QVGA screen. It has to be significant to consider this option.
