Hi everyone,
I am a new poster, having only responded to a couple of other posts here and there but I visit the forum frequently. I received my new HP35s last week and was at first quite pleased that the display was not noticeably askew. I am somewhat disappointed however at the relatively slow speed of the calculator and would like some feedback on this issue. I know it has been discussed that the 35s is slower that the 33s (I managed to sell mine), but when I compare it to the trusty 32sii, it just doesn't measure up, especially for definite integral evaluation and I do not understand why. One example is the evaluation of Vardi's integral (you can find this and other great examples on the Wolfram Mathworld website under definite integrals) to 5 decimal places; the 35s takes 00:01:46 to evaluate this integral compared to 00:01:28 on the 32sii. It takes more than 20% longer on the 35s. I have had even worse results with other programs. What's the logic behind this lack of speed, when you consider that the 33s was quite a bit faster that the Pioneers. It still outperforms the 41CX and the 15C, mind you (except for matrices...). One poster mentioned that there is always a trade-off between speed and battery life, however I will gladly bet that my faster Pioneer will still be going strong on its years-old button cells after many battery changes in the 35s. Thanks,
