A looking at the upcoming Mac OSX Leopard

Slated to be released early 1Q 2007, Apple's newest operating system is self-labeled as Vista 2.0. But from what I can tell, there are arn't that many new features than OXS Tiger. Time Machine, Spaces, and better collaboration withiniLife seems to be the only thing really standing out for Leopard. Expected to be released for about $150, I'm still undecided whether I'll purchase of it immediately or not. Here's a link for it here: http://www.apple.com/macosx/leopard/index.html
