The relative screen real estate will be different, but the size
relationship between the parts (images, fonts, table-widths etc) will
remain the same.

So does this (with screenshots).

	<http://developer.apple.com/internet/fonts/fonts_sizing.html>
and
	<http://developer.apple.com/internet/fonts/fonts_gallery.html>

The situation with font sizes is extremely pickled!
Yes Mac is based on 72 dpi and Windows defaults to 96 dpi, but it is more
complicated than this ..... for instance new versions of IE for Mac
"emulate" 96dpi, to try and limit the difference.
