It's funny to see them market the fact that Mac OS X takes up less disk space. While this is true, I'm sure the only reason is because all bundled apps and frameworks no longer contain PowerPC chunks in their universal binaries.

Bertrand Serlet said something about compression in the keynote.

Also note that the largest part of application size is not in binary, but in resources (images, nibs, etc.)

Edit: also, all major apps are compiled with 64-bit support (and should run on 32-bit systems), thus it's minus ppc, but plus x86_64, which has a larger code size.

HFS+ in Snow Leopard has transparent compression for read-only files. I think that probably counts for more than stripping binaries.
