Hi. I'm a Professional Engineer...not an actuary. However I 'grew up' during the early programmable calculator days. When the HP-41 came out I immediately bought one. On the contrary, my employer supplied a TI SR-52 (I believe it was called). I used both for complex calculations and wrote rather lengthy programs for both.Hey guys, I'm an actuary student and this semester my important math courses are Calculus 2 and Linear Algebra I besides financial math II. I also have calculus 3-4, Linear algebra II, Prob. I-II, and statistics I-II in my future.

Anyway I'm getting a calculator and I can't decide between the Hp50G and the Ti89. I like the infrared and sd flash ports on the hp but I've seen many claim that the 89 is easier to use. Another thing I've noticed is there are more programs available for the 89.

I'm sure most of you know exactly what to look for in a calc. Pleas help me out here, thanks.

First, the HP IS easier to do math and/or complex calculations. I have alot of problems using the (what I would term) antiquated method of entry/function/entry = technique of calculating anything.

Second, the HP was far superior in ease of entry for programming, the number of keystrokes (which are executed automatically when running the program) it took to enter the 'same' program for each and last but not least the speed with which the program was run.

I freely admit that the new HPs (I have progressed thru the HP-48sx, the HP-48g, the HP-49+ AND the HP-50g...all of which I own) are NOT as easy to program, etc. as the HP-41 is....at least for me. I have reverted to an HP-41cx (the last and 'best' of the line) which I paid MORE for on ebay than ANY of the newer HPs can be bought for NEW! In fact, they go for more USED than a new TI-89! I think this supports the strengths of the original HP-41 programmable calculator.

My recommendation: give the 41cx a look as well as the two which are the subject of this thread. Unfortunately I personnally can't recommend a direct answer to your question but I hope this might help in your decision.
