I had one with my older two. Honestly, I used it maybe 3 times because it took up the entire trunk, was hard to handle, especially indoors and none of mine really used one past 2-2 1/2.
My youngest will be about 21 mo when this baby gets here and I have no plans to buy one. I really have not missed having one. We live about 3 blocks from the nearest playground and if we go somewhere like the zoo or theme park we just rent a double stroller for the day. But even in the case of us renting one, it seems that we end up carrying the baby at some point so the carrier/wrap/sling comes in handy even then.
If you go for a lot of walks/running or do a lot of outdoor activities it might be a good idea.
