changing table pros and cons

Boymom • First time mom of baby boy #1
I am seeing a lot of nurseries with no changing table. There is just a pad on top of a dresser or some other type of furniture.  I am hoping to get a crib/changer convertible crib. But if not then a separate changing table and crib. 
For those that don't have an actual changing table, do you wish you had one after baby was born or are you just fine using the pad on dresser set up?
