Smaller Footprint and New Math

There’s been a lot of talk about Snow Leopard’s smaller footprint, and its “new math”.

Lots of folks have been dismissing the smaller footprint and saying gains in free space are all due to the new math.

Well, the people saying that are wrong.

Take my desktop machine, for example. Under Leopard, it reported having 30.42 “GB” free. That’s really 30.42 GiB, which converts to 3.2663x10^10 bytes*, or 32.663 GB*.

After Snow Leopard installed, I had 39.87 GB free, so even after the unit conversion, I gained a little over 7 GB of free space.
