resolution preferences??

[rakshat hooja]

The difference between the VGA screen of the Neo and the QVGA screens I have
are very clear to me (with the VGA being clearly superior) when kept side by
side. But for most of my activities including reading long emails the QVGA
resolution is enough. So unless we have the processing power to run at least
25 FPS VGA video, I would be happy with a QVGA as there is bound to be a
price and performance improvement.
