If we're digging around in human factors, I think that power indication is more important than speed. Personally I don't warm to speed tapes but that is because I spent over 30 years looking at dials. The youngsters are far more comfortable with the TV screens. However, so many seem to forget (not attribute enough weight) to the Power + Attitude = Performance mantra. Asiana crashed because of a lack of basics, together with (semi)-automation, CRM, cultural etc. Letting the aircraft manage the power, or worse thinking that the aircraft is managing the power, takes away a key indicator of how the aircraft is performing. FFS, point and power.
