The iPhone version has already received an astounding response because it, "brings GQueues into your everyday life," so you can check off your grocery list while at the store or add new movies to see right after you watch the previews in the theater. See the featured listing of GQueues in Apple's directory of iPhone web apps.
How are you using GQueues on the go?
I love building products! And Python. And dark chocolate. When I'm not leading the team at GQueues, I can be found running ultras on the trails of the Rocky Mountains.
