Well, from this laymen's perspective: Pilots have been stalling their planes out of the sky a lot longer than the electronic PFD has been around.
As the saying goes:
"Keep they airspeed up, less the ground cometh from below and smite thee" Something passed on to many a student learning to fly.
A diligent crew should be able to monitor their speed and notice a deterioration. A diligent crew with a backup crew sitting behind them doubly so. A diligent crew with instructors sitting behind them should be flying gods.
Seeing as airliners are not dropping out of the sky on a daily basis due to the pilots not being able to understand what the speed tape is telling them, I think it's pretty but a moot point.
The Asiana 214 crew screwed up.
