I am happy with Rohan. I did have a time when I was sure I wanted more, but to be honest, that inclination seems to have left the building, at least for the time being.
I dont know why, and maybe I will change my mind, but I am more than happy with the one I have and don't feel the need to have another. Obviously, I have thought of the pros and cons extensively, but I always end up back at the same decision, so I know its the right one for me.
I believe its a very personal decision whether to have one, or 15
