From: ljferrier on 27 Oct 2006 14:08 First, I must say that a calculator is a working tool for me (I spend hours working on figures, statistics, etc.). I use the calculator to compute approximations or to do verifications on the order of magnitude of a result. Otherwise I use a Macintosh and a spreadsheet program mainly. I am not so sure the HP 50g will be killed by the nspire. Below are soem of my thoughts... If we talk about the Classpad 300 PLUS or the Xpander (I have both of them), the stylus is really a problem: you keep on switching between the stylus and the keyboard and that becomes quickly very annoying. The user interface of the Classpad is certainly much more intuitive than that of the HP 50g, but once you get used to the HP I believe you are much more efficient. RPN take a part in this efficiency. The same remark probably applies to the nspire. Regarding the nspire vs. the HP 50g, I spend a lot of take comparing them on the basis of reports and description found on the Internet before buying the latter. Right now, ti seems to have a lot of problems with the reliability of their OS + batteries life (hence the delayed date of availabiliy). I also have doubts on the usabillity of the keyboard (i.e. the small green alphabetic keys) and on the readibility of their screen. Beside that, the software they have developed is clearly education-oriented not business-oriented. This latter point is a matter of choice not of technology. The main point speaking in favour of the nspire (and of the Classpad) is the programming language which is definitely more accessible than RPL. But once again, which is the more powerful? So I don't believe I will buy a nspire when it comes out (and price for a company is not a decisive factor!). I'll rather send HP suggestions for improving the HP 50g rather :-) And I am not too concerned about HP calculators future.

From: Philippe Salmon on 27 Oct 2006 15:35 Note that if you want to submit a "TI-nspire CAS Interest Form", you NEED to fill the field : "Which TI Graphing Calculator do you currently use? (check all that apply)* TI-73 Explorer? TI-82/TI-83 TI-83 Plus TI-83 Plus Silver Edition TI-84 Plus TI-84 Plus Silver Edition TI-86 TI-89 TI-89 Titanium TI-92 Plus Voyage? 200 " If you check none of them, the request is rejected ! I conclude that new TI users are not welcome ! Fortunately, searching in my calculators collection, I found an old TI-82, so I can honestly check it ;-)

Hps calculate the answer to the exact input of 3.141592654 radians to 12 significant digits, TIs do not even come close User inteface is one thing, accuracy of answers is anohter. I thing HP still wins...afterall, the main mision of a calculaor is to calculate, not look pretty.

Well seems that you like HP48 S with new CAS..... IsnĀ“t it HP48 GX ? My very old, worked and, indestructible 48S use to fit, but does not have CAS. Daniel |
