A small help!!

< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

Sir Mr Tilleson,
    I am a Software Eng. student and I'm doing a technical report about < xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Vista's new interface. I've been looking around for sources, I've found a lot actually but none of the really is just about the interface. They all combine the other aspects as security, reliability and many other features. So Mr Tilleson if u can recommend any websites that discuss this issue, it would be very helpful.
Thank you ...
