Perhaps I'm just old fashioned?
I tend to monitor airspeed, because in a typical year I maybe fly a dozen types, and don't trust myself to get the pitch attitude right when I'm seldom all that familiar with the model. Airspeed, with a little bit of maths, IS a useful guidance method. Most of the time we're also in relatively unaccelerated flight, so wings level stall speed is a simple function of weight.
Also whilst 95%+ of aeroplanes don't have IAOA available, 99%+ of aeroplanes do have IAS. We use what's there. Oh yes, and I'd guess that less than 50% of IAOA systems have been subjected to rigorous flight testing leading to proper guidance and training material on their use.
