But whats the future for those of us who think RPN???
I just updated my itouch and noted that there is a bunch of RPN applets out there for it, and the standard calculator now comes with a rather usable (but non RPN) scientific mode if tipped on its side, but not the same as the solid made purpose built calculators like the 41c or 1xc series we have come to love.
oh and the 12c does not quite cut it, sorry but spreadsheet users use the 12c, accountants are a bain of my life at certain times of the year so I will ignore thatone exists. but hey, if they can continue to make a financial 12c why not a humble 10/11/15c
