I migrated a company with 60 franchises from a broken, old, 25 MB per mailbox mail system, to Google Apps last year.
The biggest suggestion I have for anyone wanting to use the paid Google Apps is to go through an authorized reseller. You will get better pricing, and they generally have faster access to higher level support than going directly through Google. I had an absolute nightmare of a time with client support (construction workers with little computer literacy) but any legitimate problems during the transition were quickly dealt with by Google via the reseller.
Also, good luck getting a response from the Google Apps sales team in the first place.
Let's see who funded the study: (* added for emphasis)

I agree adolescents probably shouldn't partake, but for adults, there's far worse things.
