Title: Warning to HP Calculator Users
The 49G is a powerful calculator with a bad key pad.  After paying $170 for it, I'm sad to say I almost never use it.  The old 32S that I got at a yard sale for $5 is so much faster, all because it has that nice, traditional HP key pad that allows you to input values almost as fast as you can think them.  I suppose in fairness, the 49G key pad is no worse than my wife's $10 Casio, but then that was only $10 and I wouldn't use it for work, either.  Too bad they used such a poor key pad, they might have had a winner on their hands if not for that.  If I had it to do over again, I would get a 48GX instead based on the key pad alone.  Making matters a little harder, the 49G comes factory set in algebraic mode, not RPN, and the instruction manual is largely written for the algebraic mode.  Simple functions are easy enough to figure out how to convert to RPN, but some of the multiple step built-in functions are not so obvious.  To their credit, I have gotten prompt responses to my emails to their help site.

Sounds like a good idea. I'd hate to have to go back to my Casio where the (4) $1.99 each batteries it takes last for about 2 months - RPN is great. Has anyone tried the 49g, I have the 48 GX and have been very satisfied with it.

I've been using an HP28S, which HP stopped making in the mid-80's (I believe).  To be on the safe side, I picked up another one in mint condition on E-Bay at a great price and have tucked it away for future use when my original calculator may give up the ghost.

If many of you are like me, you've been using an HP RPN calculator since your freshmen-level statics class or even before that.  Over the weekend, I discovered that those of us who depend on our HP calculators may have a potential crisis on our hands -- HP may be ending its calculator development division.  You can read about it here:
HP is the only producer of RPN calculators.  I don't know about you, but my brain only works in RPN!  The switch from RPN to a regular algebraic calculator would probably be more painful to me than the switch from ASD to LRFD (a change that I'm currently undertaking).
