we tried out our moby this weekend and loved it! I wore it Saturday for a walk to the park, DH wore it Sunday shopping. baby went right to sleep both times, and the wrap is very comfortable to wear.
I've had baby in the k'tan since she was a couple days old and she does great, although she'll occassionally fuss for the first couple of minutes if she's already in a grumbly mood. She used to fit in it like a hammock and I Just always checked to make sure she had a clear airway and now she's getting big enough to really sit upright in it like the photo examples in the instructions. My partner wears it as well and he loves it. So convenient! We've always used it for running errands, I get a little anxious at thinking about how to navigate her car seat in places like the grocery store (we don't have a stroller).
Re: Anyone use their baby carrier yet? If so what kind do you have?
