There are a lot changes in Apple's latest OS upgrade

Tuesday's release of Mac OS X 10.5.7, the latest update to the Leopard operating system, weighed in at 449MB on my MacBook Pro; the combined updater (which will update any version of OS X 10.5 to 10.5.7) is a whopping 729MB. Even on a super-fast FIOS connection, it took a few minutes to download the update, and quite a few more minutes to install. It seems that the "writing files" step takes longer and longer with each update.

After waiting through the install phase and requisite reboot, my machine came up in 10.5.7, ready for use. On the surface, there's nothing visually different about this update.
