They're really speeding up their release schedule. Not really related to the topic, but I'm curious why is the Mac build twice the size of the Windows one?

I wonder if they still package both PPC and Intel binaries together. This is usually the reason why OS X apps seem to be larger than their Windows counterparts.

I think the Mac version is a 32/64 bit universal binary. That might be an explanation, anyway.

My guess is it's a universal binary.
