RE: WP32S in 2016?
what for do you want BT (when you've got USB and SD)?
Communication between units and share your data/equation/program or full backup to your phone/tablet. Sounds like belt and braces to me. And BT eats batteries. I guess the WiFi (and GPS) eats the batts, that's why I don't suggested these features also. Why do you need to stay BT ON when you don't want to use it? Possibility to use a function (because it is available) is more than nothing. If you have no belt AND/OR braces your pants drops off. backlight LCD without backlight function labels? Backlight for keys also required and for the plate of keyboard (to see the 2nd functions) Now we've liftoff, haven't we? Personally, I calculate at daylight. YMMV. Sometimes the light conditions not really comfortable under the ESP in a power plant during commissioning. What is the problem with it? Nokia 6210 phone runs twothree weeks with one charging and it have a radio inside and this was 15 years ago. Do not say that a pocket calculator can't to run with one charge to months... Why do not use one light sensor and customizable setpoint for switch ON backlight + long press ON button for switch ON BL immediately? What statistical stuff do you miss? For example I am an engineer and I have a model of a process (a diffeq). I want to make the solution with my calc and after than I want to fit the solution into my measured data. If I have an equation of this model I can extract additional informations about my process (slope at any points (how the process is fast), integration of the curve (how many material/power consumption on this interval), etc...). Two simple examples: a.) try to fit your HP48nn calc a linear function which is crosses Yaxis at Y=1 or b.) fit the quadratic function which have dY/dX=1 slope at X=0 these additional features everyday requirements during engineering problem solving. You did want a nongraphing calc. I do not recommend doing advanced curve fitting without some visual feedback. You may look at the numeric residuals though I'd prefer looking at the graph as long as possible. There may be situations where the numeric results tell you more about the goodness of fit but I'd think such applications are beyond the realm of a pocket calculator's micro screen. Again, YMMV. Sure, typically I want to fit Y=F+(IF)×EXP(K×X) shape functions to my measured data. I want to calculate F(inal) and I(nitial) values and K. In this case very helpful if you can to see the result graphically. Or other example: if you measures characteristics curves (eg. for a pump), you must to check the points distribution on a measuring range. In this case recommend to draw a "controldiagram" to checking points how equidistant the distribution. But: during this job to make plots on a tiny LCD really timewasting. Far better if you use paper and pencil and the calculator helps to make conversion between measured data and chart values. If I sitting in the office I don't want to use this function also: I like better Excel or Maple. Csaba
