as subject says, I'm searching a good scientific calculator for windows mobile.
Usually I use an Cysio fx991-MS... but if I don't have it with me... I need an equivalent replacement....which I always take with me...on my windows mobile device.
I tried lots of calculators the last days... but most seem to be totally useless or have an interface nobody likes to use...
I'd even pay for it, but is has to be simple and look like no-toy! (yapp...there where crappy things with pink color and that stuff while I was trying some tools...)
