|Calc recommendation / 39gII?|
Message #1 Posted by PatrickR on 16 June 2012, 2:33 p.m.
I would like to ask for some advice and feedback.
I'm looking to purchase 2 kinds of calculators.
I am a (small) entrepreneur in the tech sector. This means that when I'm not at a computer (using Excel, Wolfram Alpha or Windows Calc), that I always have an HP12C (what a great thingy!) and a scientific calc (usually TI) with me.
I would like to lighten the weight of all this, but still have financial and scientific calculation power. I don't use smartphones.
So I'm looking for:
1) a very pocketable scientific/financial calc (the gold medal would be something that handles both financial & science math).I would like to have something smaller than my present combo (high school scientific & HP12c) that's always in the briefcase. I've seen that there are hp12C clones in other form factors, but they don't have all scientific functions and can't be found in Europe.
Is there something that is like the proposed µCalc from DaveJ?
2) A top of the line graphing calc for when not using a PC. My TI84+ is very nice, but the graphic is a bit slow, there is no "pretty print", and its integral functions are very basic.
I liked the TI89, but I was thinking that perhaps the HP50g is better. I especially like that there is a big stack and RPN as I like to see all the numbers so I can "play" with them. (I have never tried one). Although the majority of the time I use my TI84+ which I know inside out and with my eyes closed, I think a RPN is a good addition.
The Nspire models seem very nice (I haven't used one yet), but I'm afraid that the workflow is too slow (worksheets etc,). I like being able to punch in my operations directly. Any input on experiences with those calc is welcome (though it seems that they have new models almost every year?)
Is the new HP39gII in the league of an hp50g (minus RPN)? The little information out there makes it look like a powerful grapher.
At present I have:
HP12C & TI BA+ pro, TI84+ SE, several high school scientifics from Casio & TI, and I'm going to buy the DM-xx-cc line when they are available.
and I have played with
