Everyone has a different life style, so I'd say some use it more often than others, but I doubt very seriously if any stroller is just sitting in a garage collecting dust.
I take mine in malls, walking around different towns in the summer when the asphalt is too hot for them to walk on and so on. I also like having them in the stroller when we go to any of the outside eating places. Otherwise they would get wound around table and chair legs.
If it wasn't for the stroller, they would not be going with us as often as they do now.
