Based on all of the comments that I've received, I purchased the Plus=20 version of RealCalc. It looks good so far - the only disconcerting=20 thing was failing to recognize that the "ClrX" key was the red=20 left-arrow key. That took only a few seconds to figure out, but I=20 *was* wondering for those few seconds . My only gripe so far is that I find the number of exponent digits=20 excessive - I have the display configured to show 2 decimal digits=20 (0.00) in Engineering mode and the exponents show up as 3 digits (1uF=20 shows up as 1.00 E -006) instead of 1.00 E -6. Does anyone know if=20 that is configurable? I can see that this is going to replace my stable of HP calculators -=20 its just too easy to slide the S4 out of my shirt pocket, no matter where I= am. Thanks again for all the suggestions! dwayne At 12:27 PM 6/3/2013, Neil wrote: >I use RealCalc (by Quartic Software) -- works very nicely! > > >Quoting Dwayne Reid : > > > Good day to all. > > > > I was in the market for a new cell-phone and was waffling between > > Blackberry Z10 / Q10 and one of the new Android devices.
