2006 model is disappointing

The car seat was redesigned for 2006. the new model looks extremely uncomfortable for infants. It's too upright and has no infant insert. My baby's head AND upper body just flops forward. Not only does this posture look unhealthy and uncomfortable for him but also I can't imagine that position would be safe in an accident. In addition, the seat is so so big and heavy that I envy people with the smaller car seats, whom get to lug their babies around in them. I refuse to detach it from the car, it's just too hard to carry around, and I'm a relatively strong woman. Also, the handle and adjustments are hard to reach and use. I wish that I could return the item! One would think that such an expensive name brand would be a safe bet as a purchase. Guess not!
