@noiob its kind of hard to design a calculator for ipad which doesn't look ridiculous. best throw would have been an applet design, much like the calculator on mac os.
i guess this was the reason why the first ipad never included one. still, kind of embarrasing how long it took for them to figure out the obvious things.
generally, calculators and steve jobs really never were friends at apple, on the original macintosh steve jobs was upset with most designs which drove developers to create an application where jobs could design a calculator to his liking.
@noiob yup, pcalc was an obvious choice for me, as its a veteran app on mac os, handwriting to calculator never really was something i strived to have.
alas, finally no one has to buy or install an third party app for calculations.
