| PA4TIM:
I can choose between a sharp PC-1211 and a 1500. During my study my uncle boreed me his Sharp and I think it was a 1211. But hat was around 1983 or 1984 so I'm not sure. The man I'm repairing the 9100 for has both and I can get one. I think the 1500 is more practical because it has more possibilitys and uses regular AA batterys ( they are both with the printer) ( i'm afraid calculators are like multimeters, they multiply. Allready have 3 HPs and 2 casio's and a bunch of HP apps. Think I would like a HP-65 42 and 48 but then its enough, ( something tells me this oes the wrong way. ;) ) |

A HP -35 the mother of all scientific pocket multimeters --- End quote --- thats exactly what you need! 99% of everything you'll do can be done with that calculator, and none of the really useful functions are buried beneath three layers of shift and mode keys. When it comes right down to it, everything else is just window dressing. All the stuff you need is just right there at your fingertips. Brilliant functional product design. The only thing I might add in would be a few brackets for nested calculations, degree radian and gradient modes, and engineering mode just because occasionally I like to be lazy. |

I think they look rather gimmicky, but I've never actually used one. I'd assume battery life must be atrocious. I really like my current calculator (Sharp EL-516X) because it has dual power (solar + battery). Never have to change the batteries in my calculator again. I wonder if there's any use for e-ink in calculators? Might be interesting. Anyway, any thoughts on those smartphones with calculator software running on top calculators? --- End quote --- I got both a Ti nspire touch (B/W) and the CAS colour version.. and they are truly great, i would say the most advanced and best calculator in the world today! They are truly enormously powerfull.. You can have 4 windows (yes like on the PC) at the same time and it multitasks simultaiusly between them. TI claims this new color version will last 2 weeks between charges if you use them on daily bases. Just watch the video.. i just cant start to say how great it is. The CAS version is just a mini PC.. and with them you get a software version of the calculator for your PC. And its Vernier function lab equipment connection, with sensors, (yes even voltmeter) is just great for data collection. but they "cost a little". DOOM and gameboy games also run on them !! So my old 30 years CASIO FX-720P is resting now.. but that is also a truley great calculator (Basic programin language). |

But as far as usability? I mean sure it's powerful, but do you think yo make any sacrifices using one of those? |
