The Reality of Data Transfer - Pigeons :-)

There is a great example of data transfer challenges done in a humorous way:

As Engadget stated:   "Unlimited IT, so exasperated by South Africa's leading supplier of slow internet connectivity that it pitted a Telkom ADSL line against a real-live homing pigeon in a 60-mile data transmission race. The pigeon arrived with the 4GB memory stick in just over an hour with another hour required to load the data onto the computer. As for Telkom? Well, after 2 hours it had barely reached 4%."

The canonical example of moving lots of data is the truckload of DVDs or the 747 full of DVDs is faster than wirelines.
