Pre-AOS TIs--And they say RPN is complicated!?

In TI's sales literature (especially with the SR-52/56 literature), TI mentions about their choice of AOS instead of RPN. Even as I have my eldest sister's SR-50, lookng at its parentheses-lacking keyboard, I'm still stunned, befuddled, and perplexed that, although pre-AOS, TI's entry system was an improvement over RPN.

Do any of you here see any logic (yes, pun intended), common sense, or intuitiveness to problem solving on an SR-50/50A, 51/51A?

I didn't own an RPN/L machine for many years - HP's prices were way too high - and so I grew up with algebraic entry. To me, calculators were miracles and if I had to jump through a hoop or two to get to the correct answer, perhaps storing or even writing down intermediate results, it was still far far faster than the alternative. Algebraic /AOS works fine if you are used to it!

Also, I can see the marketing appeal of a machine that lets you type "2 + 2 =" and has "4" appear in the display, rather than "2 ENTER 2 +". If a product is aimed at home users or students then the marketing advantages of algebraic cannot be overlooked. Even HP succumbed eventually, I imagine for this reason!

Which do I like best today? I like what the Prime offers - algebraic, with the ability to scroll back, retrieve previous results and edit previous entries. My Prime is not set to RPN mode. Sorry!
