Don't know yet if you're going to TechX World? Maybe these two short YouTube videos will help you decide!
First view this amusing couple of minutes that promotes the TechX World interoperability conference (produced by Windows IT Pro), which is coming soon to a city near you.
And if you think you don't need to go to such conferences then check out this 57 second clip, where David Letterman might remind of you why you probably do need to go (or at least he might remind you about why you have a heterogenous environment).
LOL ! It's all in good fun :-)
