Mac or Windows...?

[SNIP]
A major advantage of the Mac is the Quartz graphics
device. Graphics quality on screen is much better and
it is possible to copy and paste graphics without
quality loss to other applications.

I agree with most of what he said here. I would note however
that we routinely have to use the X11() device instead of
quartz() device in R due to speed issues. I have code that
would take several minutes drawing a heatmap using quartz
device. One day I accidentally started X11 device instead
and found the same code executed in about fifteen seconds.
