Top Customer Reviews
The bad: Slower all around compared to B&W TI-84s. Mathprint features not implemented as handily as they could be in favor of keeping exact same layout. Not much new in the way of features.
The ugly: Sluggishness can't be fixed as it's the exact same hardware with a greater workload (that fancy LCD). No programs/apps for normal TI-84s can be used without being updated.
Basically, what the TI-84 Color boils down to is TI bolted a color screen and a rechargeable battery onto the good ol' TI-84 and called it a day, without upgrading its elderly CPU. As a result, the calculator is slower everywhere because it has 12 times more pixels to drive. UI is where it shows the most. Graphing is relatively quick so long as you turn off asymptote detection in graph format options. Turning it on (it's on by default) reduces it to TI-83+ speeds.
No existing programs or flash apps can be used without the developer updating them. If you have an app you simply must have, DON'T GET THIS CALCULATOR! A lot of programs are no longer maintained, and the ones that are will require varying degrees of effort to be ported as the display slows things down a lot. Games won't work period until a faster display method is found.
Conclusion: Do you own a TI-84? Good, keep it and don't bother with the color version. If you don't have one, and need to buy one NEW, you may as well get this, seeing as it's only 10$ more. Used TI-83+/TI-84+ are way cheaper, though.
3 stars. Not majorly deficient, but nor is it outstanding.
Technical rant: In the day of carrying multi-gigahertz CPUs in our pocket, the least TI could do is grab a more modern member of the Z80 family, like the EZ80, which is 4-11 times faster than a Z80 of the same clock speed. Software modifications would be minor as it's binary compatible, and the benefits manifold. Faster everything, more RAM (up to 256 times more!), more powerful software, longer battery life... the cost to TI being that they'd have to design a newer PCB, which would eat into the truly ludicrous profit margins on these calculators.
Software changes required would be minor at best, which is hilarious because of the effort TI had to make to port the OS and flash apps to a newer display - which broke all existing programs for the TI-84. If they were going to semi-break backwards compatibility, they might as well have done it for the sake of an upgrade.
Even jettisoning the ancient TI-83 layout in favor of a layout similar to the TI-36x Pro scientific calculator would have been a worthy improvement. Nope, too much effort. Sigh.
However, TI have dropped the ball in a number of places with this upgrade and they are serious enough to be both annoying and to lead to getting the wrong answer.
1. The graph drawing is markedly slower than the TI-84. For example, a plot of y=cos(x) in radian mode and standard zoom takes over twice as long on the 84C as on the 84.
2. There is a lag in the keyboard that can lead to missing keystrokes. Considering how fast the modern texting kid can work a keyboard, that can lead to some odd results and I am constantly having students ask me what's wrong with their calculations because a keystroke has gone astray.
3. Most seriously from my point of view as a teacher is that TI have not made the Smartpad app available for this calculator so if, like me, you have been used to teaching the use of the calculator by using Smartview and Smartpad together, you are now officially out of luck and have to use your PC's keyboard which is significantly slower and more error prone than using the calculator for computer input. Based on this alone, I would recommend looking for a different calculator as your school's standard (and no, I don't know if any other maker's calculator has this very useful and basic feature).
I can only hope that a future OS for the 84C addresses these problems as right now it looks like this calculator is just a repackaged version of some very old technology.
I also have to mention that in comparison between my ti 84 plus and my ti 84 plus c silver edition, the ti 84 plus c silver edition lags behind. While it is noticeable and does become quite annoying, the speeds are not horrendous and you will get used to them. It might take a second or two longer to graph a function or a second to open a menu. These speeds are not terrible by any means but on a timed test, these seconds could add up.
I've told you some positives and negatives of the calculator. After spending a day with mine, I'll never go back to my old calculator. You should buy this calculator if
1: you need a higher pixel density color screen
2: if you would use some of the new small features mentioned in the review
If you are looking for a speedy calculator, I would not recommend this but recommend the ti 89 or one of the ti nspires.
