[nmglug] open source advocacy presentation,

[Andres Paglayan]

Guys,

Besides the philosophical believes,

If you had one hour with regular people to explain why using open  
source instead of proprietary tools,
more specifically, why using openOffice instead of MS office,
and why to avoid being trapped into exchange (who doesn't play with  
others)
and into ie6/7 browsing exclusivity and so on,

What tools will you use to explain this?
are you aware of any presentation already made?
(ppt are fine, ;-)
or any resource in the web to start with?

Thank you,

Andres
