Difference b/w SCCM 2003, 2007 & SCCM 2012 ?

Hi guys,
Every one knows that SCCM is a very powerful tool to manage IT Infrastructure. SCCM became popular from 2007.

Actually my this post is all about the SMS 2003 ,SCCM 2007 & SCCM 2012. Recently i was just checking the difference among all SCCM versions and i found a very good stuff on net.So i thought i should post it...

Very less people (including me to)know that "what is the difference b/w SMS 2003 & SCCM 2007 & SCCM 2012".
