Well, EAA is still in its infancy. There are electronic telescopes like the Vaonis Stellina (80mm) and the evScope (115mm), costing $4000 resp $3000 (USD, not AUD) respectively and only moderate performance according to some reviews on CloudyNights and DPReview. An average AP setup with a (even APS-C) DSLR or ASI astrocam + ED80 costing less performs better, so they are the worst bang for the buck.
But I guess that in the 2020s better and more affordable devices will appear.
What I hope is that there will appear an electronic eyepiece to be popped in any telescope which transfers images to smartphones or other display devices.
