    Question HP Calculator Questions

    Hi. I am currently using a TI-89 Titanium calculator, but I have been thinking of getting a new HP Calculator because I have a problem with my current calculator. Before I change from TI to HP, I have a few questions about HP calculators:

    1. What is the difference bewteen the HP 48II, 49+ and 50?

    2. What is the difference between a HP 50g and a TI 89 Titanium?

    3. I read that SD cards can be used for memory on a HP 50g. Can any SD card be used, or do I have to buy a HP one.

    4. I read that people have had problems with keys "getting loose" on some HP calculators. Could anyone explain this problem to me, and which calculators are affected by this?

    Thanks for your help!

    The 48II is so different from the other two that it would take several pages to enumerate the differences. Suffice it to say, it is the older of the machines.

    Basically, there are hardware differences between the 49+ and 50G. Go with the 50G. IMHO it's much better.

    Many differences, but the one thing I like best is the display seems clearer on the 50G. It's been said before, but bears repeating - the 50G is in general harder to learn but more powerful.

    The 89T has a larger support group and a lot more programs available for it. TI owns the education market, so that brings along a lot of pluses too.

    The 50G is a hacker / programmer's machine and I wouldn't trade it for any other calculator. I have my doubts if we'll ever see another calculator made that is as powerful and programmable as the 50G owing to present market conditions.

    I use a 1G Kodak card in mine and have no problems with it.

    That was a problem with the HP-49s. The HP-50G is a far more rugged machine and has no such problems that i'm aware of. (I've owned and used mine extensively for almost four years and it still looks, feels, and runs great!)
