I rarely leave home without it because it can be used for so many different reasons. I also don't have another portable device that has the features of an iPad, e.g., a smartphone. I primarily use it when I go to work, but when I'm out shopping alone, I frequently use my iPad 2 to take photos of store items (with permission) so my spouse and I can discuss them before deciding on which one to purchase, to scribble down info in my note taking app instead of using pen and paper, and the usual activities like reading and working on a project while in transit, etc.
