To paraphrase the script for the movie "Airplane! II":
"First, there was the Big Bang. Then the Earth cooled. And then the dinosaurs came, but they got too big and fat, so they all died and they turned into oil. And then the Arabs came and they bought Mercedes Benzes ... then the Raspberry Pi was announced and we waited and waited until it showed up after we had forgotten we ordered it, and it was even better than we had expected ... "
The best things in life aren't things ... but, a Pi comes pretty darned close!

In theory, theory & practice are the same - in practice, they aren't!!!
