Really like the CAS system that solves, simplifies, factors, expands, etc. algebraic expressions. No need to convert systems of equations to matrices. No worrying about silly mistakes in algebra. I really like that expressions can be variables, makes substitution super easy.
I'm coming from a TI-82 (it still works!) so I felt fairly comfortable, but still had to watch a few YouTube videos to get the gist of documents and an overview of the features. Read the manuals, watch videos, google, etc and the fun and power slowly reveals itself.
I installed the software, calculator comes with a license but you have to download from TI's site. Used the software to upgrade the firmware to latest version no problem, transfer files to and from calculator, and the software emulates the calculator so you can use your computer for editing, screen sharing, etc. All very cool.
Build seems solid, though not as rugged feeling as my old TI-82 which is built like a tank and survived many drops and abuse. Bought a padded case for this one, which I don't think is needed for the older models.
Does the product work? yes. Was it new? No.
I would not have paid what I did if I knew it was open. Would not buy again from this particular vendor.
Want to store values on the fly so you can plug them into equations? Use "i_1 := ans" and your last value is now stored as i_1
Want to write a formula on the fly so you're less likely the mess it up when doing it multiple times on an exam? "coolFunctionName(x,y,z,p) := (x^2 - p*y/5)/(z(z+5/2*p)". Now you can just enter your 4 variables "coolFunctionName(var1, var2, var3, var4)". Problem solved. I wrote a function that calculates parallel resistors. When you have 3+ parallel resistors, this is a huge time saver.
This also lets you type out equations as you would write them on paper. Instead of just having a string of variables and symbols, you can clearly read your equation to reduce entry errors. Spend less time balancing parenthesis and more time getting work done.
It does so much more than the TI-89. Solves problems almost instantly. There is a small learning curve because it works differently than other TI calculators, but it is so much quicker to use and so much more powerful. This latest version will even help with some rudimentary differential equations. It lets me focus on the material I'm learning not spending unnecessary time computing tedious equations I mastered a year ago that are bringing minimal learning value/time spent.
The programming language is still a little more rudimentary than I'd like, but it's very useful.
