I suppose a calculator with infix entry wouldn't be so bad if it
I always had fun with the Casio FX-7000G, the first graphing calculator from
'85. With a whopping 422 bytes of memory and holds 10 programs with a huge
96x64 pixels display. Mine's a littlle dusty now, but still works. I heard
some schools outlawed these in the beginning cause it was so easy to cheat
;)

would store the entire entry until the = key is
pressed, then
evaluate it observing rules of operator precedence.
But none AFAIK do, so an infix calculator really isn't.
I take it you've never used a 'graphing calculator'? The TI-82, TI-83,
TI-85 and probably other models all do exactly what you describe, and have
been selling 1 per high school student in the USA for some time now...
