I see where you'e going with this, but I might change your examples a little bit. There's a very fine line between just a simple Google search and a lot of what you're showing there. It might make sense to demonstrate something that requires more human intervention. The file conversion example is a good one, and maybe expand more on assembling trip itineraries, etc. IOTW, things that actually would take up a lot of time, where the value of the site would be more clearly demonstrated.
