Shifty saved my bacon yesterday afternoon. My phone was dying. The convention center has charging stations but none of the chargers fit my phone. I managed to hook up with the rest of the team. Shifty, always two moves ahead, brought his charger (he and I have the same phone) with him to the show. Voila! Phone charged and good to go.
I followed his lead and brought my charger today (charging as I type this).
The convention is awash in different languages. I'm no linguist but I believe I've heard: British English, Japanese, Russian, Hebrew, Arabic, Spanish not to mention some horribly accented English. I'll wager their English is still better than my attempts at their language.
Attendees range from the very, very young to the very old. Sweats, jeans, khakis to suits--men and women are wearing it all.
At the risk of sounding sexist, there are a surprising number of women here for what is traditionally a male-oriented and -populated area of interest. I don't mean "booth babes" (although they are here, too); women are running booths, representing buyers, discussing product and making deals.
A good thing, in my opinion.
