though most of it is under the hood and won't be needed until software is updated to use it (ie: Grand Central Dispatch, OpenCL). If you have the time, check out Ars Technica's in-depth review of Snow Leopard:

One improvement I see a lot is iChat - it uses 1/3rd the bandwidth and yet has an increased picture size of 640x480. I imagine it's using OpenCL to facilitate the higher compression. Another I find handy is when you try to eject a disk that's in use - it now tells you what application is preventing it from being ejected.

One change I find annoying is it now reports disk and file sizes using market speak - 1K = 1000 bytes, not 1024. I suppose it deals with the things like this post - Got my new Imac with payed for a 500 gb Hd and got a 465.44gb

but it's annoying when my 32KB Atari game gets reported as 33KB as it makes me thing it compiled incorrectly.
