Bert - just goes to show how context is everything, I thought it was a play on a culturally popular street drug in the West, eXstacy. Either way, humor to be had.
Thus my joke about you being an X dealer - or at least a Verizon dealer.
My daughter got her X yesterday, and I spent part of today at a client site activating new Blackberrys and iPhones on their BB and mail servers. At one point I should have stopped and taken a picture - had a whole slew of new smart-phones scattered over a desktop in various states of configuration.
Don't worry Bert, Christmas is coming!
