I know how you feel. I went to a yorkie meet up and many of the people around me had smaller yorkies...average weight around 2-4 pounds. My yorkie is bigger at 6 pounds, and you can definitely see a size difference. Also, his coat is still wiry..but soon it should grow out and hopefully become nice and silky, as he is still a puppy.   
I'm sure you have a yorkie!!!
