Thanks Adler for the post. I really don't mean to come across as a jerk and sorry for appearing dismissive. And again for the record I would like to fly in a plane with direct AOA readout as I said, would be fun and heck I always like to get as much experiences in flying as possible.
I'm also not "negative" about AOA. I see the utility, but a few on here had an almost religious fanaticism about it that I usually only see people get when talking about the latest Apple product.

If somebody wants/needs it in their craft go right ahead.
I see a lot of disrespect for the skills of the GA pilot which is very confusing to me then I talk or fly with few of them and am positively blown away by the lack of skills or knowledge base often present. There is a wide range of academic and aeronautical ability and physical hand-eye type lacking that is (hopefully) not present in the pro community where everybody is held to recurrent training and higher standards. Again I will have to watch for this in myself (as you guys will too after you retire from pro duties) as we age and we all fly less than we used to. Ego should not enter in to the equation.
The conversation seems to have shifted to AOA as a "training aid" and again that would be potentially useful in GA planes for somebody who perhaps does not really have a good understanding about flying, how lift is generated, induced drag curves, etc.
I still have difficulty seeing the day to day use for the average GA pilot who should not get anywhere near an accelerated stall regime but I do agree it would be interesting and useful in training. I upgraded to glass and feel it has HUGE advantages, and makes IFR simpler, and is a fantastic thing. I don't argue that everybody should do so.
