Thanks Mark. Fantastic coverage, as usual.
Ron Cook is an absolutely top bloke (to belie my downunderism). He thought nothing of giving me a few hours of his time on a tour of the LM factory in Florence earlier this year, including showing me the GB-5 and making me about ten thousand espressi.
A little bit of trivia; La Marzocco is the name given to the lion with its paw on the shield. It is the florentine logo, associated with victory and adopted by LM because in the old days they had to really fight for every sale. I gather that the fact that it is a proper noun is what allows the o ending ... but that's just a guess.
Great coverage Mark - when I arrived Friday, I asked if there was much seating for Jane Goodall's speech. Your estimate of 1000 is a bit off - there were 2800 chairs set up. I don't think, aside from a rock concert, that I've ever seen so many chairs in one room. Now that I'm back from the show, I think I need a holiday to recover (and I'm sure you do too)...

I have to chime in a little bit about the comments made regarding the new La Marzocco GB5.
Number One: I think Mark's thoughts that the GB5 requires "more" purging than a Linea in the case of the machine running out of water needs a little more clarification. During the WBC when that very situation occured, the concern was that air had been pumped into the boilers and I was not comfortable releasing the machine until we were sure that any air that may have entered the system was completely purged.
Having such a situation occur during a critical event like the WBC is not something to take lightly. If air is trapped in the boilers it can create temperature instability but more seriously, air in the steam boiler can blow out, causing the milk in the pitcher to explode out with the burst of air. It's no fun and not a chance we wanted to take at the WBC.
In order to correct the anomaly, the steam boiler must be completely purged and the brew boiler must be bled out. This takes a bit of time due to the large steam boiler capacity, the grouphead purge and to allow the machine to return to it's optimal operating parameters.
