+1313 hey guys, a really amazing calculator i've installed and love having is on my phone. It's fast, accurate and vibrates gently with button pushing. As well it is has all the functions to solve what I need. It is Scientific calculator by Scalea software. So now is my question. Do you know of any proper calculator that would have similar vibrating feedback for buttons and or a similar touch screen to the smart phone. (can't take the phone into the exam to use it unfortunately.
