I don't know if anyone told you that prior (apologies, but I'm not reading every reply to know whether it has been stated) but it was explicitly mentioned in my college, and my college wasn't even a good college. Oh! I had a TI-Nspire CAS (not the CX color model) and liked it very much! Sorry that I don't have experience with the Casio, but if I can tell you something:īe VERY careful with the TI-Nspire CAS models! While it's a great calculator, the fact that it has a computer algebraic system (CAS) installed in it makes it ineligible for standardized testing, as well as most, if not all university classrooms. If you are just interested in crunching numbers ie for physics or engineering, you may be better off with a graphing calculator. If you are learning math in a classroom where you explore with a math tool, the first three definitely provide a nice demonstration.
Ti-89: High end button pushing graphing calculator with CAS. Ti-Nspire: Educational math tool (pocket math computer with color screen) Hp Prime: Educational math tool (pocket math computer with color screen) It is a high end graphing calculator, not an educational tool.ĬlassPad 400: Educational math tool (pocket math computer with color screen) No, it doesn't have color, nor anything more than a functional calculator interface. The Ti-89 is far older than the Ti-Nspire and has an excellent CAS as well. The Hp Prime supposedly has a better CAS. This makes it a somewhat less powerful number crunching tool than the earlier Hp 50G unless you use the Hp 50G in algebraic mode, then the Hp Prime is probably better (this is due to the fact that the Hp 50G is an RPN calculator by nature that was converted into an algebraic too calculator). The Hp Prime copied this philosophy as well as built their Prime upon the earlier Hp 49/40G platform. The CP400 looks to be along the same lines, but I cannot say with any authority that this is true. You do statistics, you enter a statistics app, none of the apps are actually integrated seamlessly ie you move from one to another. This new CP400 uses the same applets type interface. You should be able to review the CP300 (aside from color touch screen) to get an idea of how good its math capabilities are.Ĭasio's as a rule do not equal Ti or Hp in actual computational features or abilities. But those are my opinions only, you may want to do some other reviews. For Ti, I would prefer the Ti-89 over their Ti-Nspire. For Hp, I would prefer the Hp 50G over their Prime for my own use. But Computer packages are also available and definitely a step up in capabilities. I would rank this unit last of the three (though it probably outsells all its direct competition, and will continue that trend).īoth the Hp Prime and Ti-Nspire provide enough horsepower for the typical undergraduate. Uses a mouse like pad for screen navigation, again tough to use initially compared to touch screens or stylus. Keyboard feels tight and cramped, but this impression might change under use. Maybe so, but with close to a ten second boot up time, physics problems and thinking can become distracted. However it feels like a dedicated math computer vs calculator. The fonts are small (the screen is good, but not as bright as my Prime). I don't believe you can get one with a touch screen.
The Ti-Nspire CAS color has been out for several years and is the oldest (most mature?) product of the three. Has a 1 second boot up time from a cold start (barely noticeable). It is a tool for education, keep in mind this evolved from the Hp 39/40G product line and not Hp's higher end Hp 48/50G line (This should put a lot of observations in perspective). It is still getting firmware updates every few months, indicating there are a few bugs yet to find.
Pretty good calculator, I wouldn't say great. Charger is micro-usb, easy to find if you lose furnished charger. Fairly good battery life, 2-3 weeks on a charge, probably about 1 under extensive use. Keyboard color sux as one shift color is orange on a silver back plate, difficult to impossible for some to see. Screen resolution and color are very good. It is a touch screen (without a stylus, but a stylus should work). The Hp Prime has adopted the Casio type dedicated applications similar to the earlier (and present) Casio's. I can't provide any actual review though. I suspect it may be the nicest to use of the three. I don't have a CP400, but the screen looks great and the stylus looks to make screen manipulation very precise.
