We've come a long way

[Matt Agajanian]

Hi all.

I just had quite an amusing conversation with a friend about, of all things, the progression of calculator entry logic methods. We traverses from the parentheses lacking SR-50 to today's monumental jump into direct logics such as Equation Writer, DAL, MathPrint and Casio's VPAM.

In addition, we discussed the technology leaps from register-based variables to the abilities and functionalities via direct algebraic and symbolic equation handling. Both, unheard of in the pre-HP-28C/28S days.

So, in light of the HP-65 and its mag card programability to today's capabilities of direct formula entry, full graphics as well as extensive symbolic math capabilities of the 50G, I say we've reached quite a plateau. Just as well, how do you see the calculator progress from these impressive tech achievements?
