The wife has been a bit of a PB skeptic (though she's used it a lot more since P vs.Z came out )
She's flying down to Calgary for a couple of days and wanted to print her car rental confirmation off Hotwire.com. "Watch this!" I said with an evil grin as I installed the Print To Go driver for her.
I walked her through the configuration ("Will I have to do this every time?" "No"), and when the confirmation appeared on her Playbook she was impressed. Then she repeated it all on her own for her flight itinerary, and said, "I love this!"
