Amazingly, there was free wifi on the Mexico side of the border crossing at Tecate.
It took Shelley about two minutes to go from "cool!" to "why don't they have a better connection?"
Admittedly, that's because we moved forward in line and lost the connection.
But it reminded me of how quickly our customers go from "wow, what a great new feature" to "this sucks, why doesn't it do xyz as well?"
