There's a fallacy in there--the quality of the workout is determined by the person, not the machine. One can put the exact same effort into riding the aero bike as one can the non-aero, the rider will just go faster. Likewise, there's nothing inherent about a non-aero bike that forces you to make a serious effort.
Basically, there's really no direct connection between the amount of resistance and the quality of the workout, the rider can dog it on the non-aero bike or the aero bike, or kill it on either.
