To me a lot of it is the condition of your roads. Here in the frost belt I ride my front suspension hybrid with 700 X 25 tires commuting in the spring until the salt is washed away, the gutters get swept, and the potholes are filled on our beat up roads. Some of us have spent a lifetime of using our knees & elbows to absorb shocks and do repetitive motion work and they don't really care to be doing that anymore. When I move to my road bike after a few weeks there is a noticeable difference. Yes, you "waste" some energy, but if you're not standing or hammering, it's negligible. If you feel the need or want for front suspension I say go for it. No one here can know your personal conditions or needs. On the other hand I personally see or feel no need for suspension seatposts which often also come on these bikes.
