I downloaded VLC 2.0 for Mac. It was a 42 mb download! The corresponding Windows installer is only 21 mb, despite the extra code for the installer itself. But even worse, when I open the VLC dmg, the actual application itself while being copied to the Applications folder was 160 mb! I've noticed this with a whole lot of mac apps.
Why are mac apps so much larger than their Windows counterparts? And why is there such heavy compression? Does that mean the way they're stored in Applications is inefficient and they could be packed much smaller, or would there be a processing penalty for that?
