Well, yes. It is to avoid scaling and still provide web components
(buttons etc) that have a clickable size.

Basically most services such as GMail Mobile etc have lists and
buttons optimized for the DPI of the iPhone, thus there is no scaling
with a device-width of 320. If on the other hand you use a
device-width of 480 the list items and buttons become small and harder
to interact with so Android and Fennec (and us) considers the DPI
difference (160 vs 240) and scales everything with a factor of 1.5.
This results in us not having a pixel for each css pixel, using scaled
images etc.

This is something we want to avoid in order to make web apps look as
native as possible, plus making them take advantage of our better
