I think the observation about being able to see the entire equation on the screen versus what you last typed in regards to an AOS is spot on.
In an involved calculation, an AOS style calculation was almost guess work, especially when the key being hit doesn't change the display (like a open perentheses on a TI-58/9).
But when you can type out the entire equation "just like in the book", the dynamic changes completely, and the ease of straightfoward translation makes the machine very intuitive and easy to use.
Another thing you sort of mention regarding the SHARP was the fact that it was sold by Radio Shack. You really can't discount the effect Radio Shack had on the computer market of the day, and the visibility of having something like the SHARP in their catalog, or at a neighborhood store is quite important vs the smaller market and distribution of HP. (And personally, their Model 100 is simply one of the finest machines of its type ever made.)
My father had I think all 3 of the "Pocket Computer" models from Radio Shack. I had to snicker when I saw expresions like "AA" and "AAA" in your SHARP examples. It reminded me of one of the frustrations my father had with normal BASIC. In normal MS-BASIC, obviously AA doesn't mean "A*A", rather it's the variable AA.
But my father commented on how he had problems with his programs because he'd "run out of variables" in MS-BASIC. He'd use A, then AA, then AAA. In MS-BASIC, only the first two letters mattered -- so AA == AAA.
But you can imagine what the code looked like (especially by todays standards) being scattered with essentially meaningles variable names like A AA B BB CC Q XX etc.
