Rating + 5 Nothing More I'll Ever Need


Pros: Has tons of preloaded applications. Graphing is fast and really easy. Actually everything is really easy to use on it, especially if you are upgrading from a TI-85 or TI-86. Then you'll wonder how you lived without it. It definitely is making my Calculus and Physics classes easier in many areas. I really, really like this calculator.

Cons: Doesn't have Vista drivers only XP 32-bit. No 64-bit driver support or Vista yet. Which really made me frustrated because I run Vista and Windows 7 x64. I have to pull out my old PIII laptop with xp home to manage any applications from the web and backup data.

Needs more or expandable memory I filled it up real fast with just a couple unnecessary apps and a game.

Other Thoughts: Basically like a little computer of its own. It has its own operating system and everything. Clock, Calender, Text editor, notes. TI just needs to get on the ball and release TI connect with 64-bit drivers, I mean come on after all wouldn't the majority of the people using these things need a powerful PC. Capable of more than 3gigs memory. I just don't get that part.

Rating + 5 Way to hard to figure out


Pros: Ok, I give this 5 eggs because it will do anything you want it to. I'm a Sophmore in College, and I bought this for my STATs, Chem, and Physics classes. It will do anything

Cons: I would have given it 2 eggs at best because this this is so hard to use. Everything I learned in class I had to go on line to figure out how to do simple things on it. If anyone is in Stats, to figure out the standard deviation, it took 8 printed pages to explain how to get there. If you mess up once, like forget to press the buttons in the correct order it will give you some answer from a previous table or just give you an error screen. Unless you are an Engineer, or are going for your PHD in math stay far away from this as you can. I am sooooooo, disappointed that I spent so much of my money on this calculator.

Other Thoughts: In all honesty, I am selling this and going back to the TI-83, it's simple to use. I just hope that I can get half of what I spent on this.

Rating + 5 Great Calculatore


Pros: I need a statistical calculator for stats class, I also need one for Physics next semester. This calculator can do anything, period.

Cons: The book doesn't help that is comes with. However, everything I had trouble with was easily found on the internet. The only thing is this thing is a computer basically, and is really intimidating at first. If you don't need something really technical, I'd go with the Ti-84, but if you want a calculator that will do everything besides play DVDs this one is for you.

Other Thoughts: Quick summary, awesome calculator, but hard to get use to. If you are in high school/ college this thing will come in handy. But like said before the cheaper models are easier to use.

Rating + 4 Nice


Pros: Awesome calculator, you can do pretty much anything you want on it.

Cons: The one thing that kinda suprised me was there is no Log button, or even Log function, you have to do it the long way, and that kinda sucks if your taking calc

Other Thoughts: I would recommend it to anyone :)

Rating + 5 Awesome


Pros: This is an amazing calculator. It will do all of the calculus and trigonometry functions. It also has all of the algebra and statistics functions. It comes with over a dozen applications pre-loaded that have everything from gambeling probability to a calendar. It has a usb port so that you can add even more applications for engineering and chemistry and numerous other things. It has an amazing battery life, and is very durable.

Cons: When you first get it the cover is very stiff and hard to get on and off, but this works itself out after a few weeks of regular use.

Other Thoughts: These are good for everything from simple math through college and beyond.

Rating + 5 Ti-89 School Use


Pros: Great Calculator if you are in (Algebra, Trig, Pre cal, Cal I, Cal II, Cal III, Diffyeq, ETC) Calculator is also great for all my engineering courses (Mechanical). Has pre programmed electircal Engineering equations. Performs Integration, Derivatives, Graphs (3d, parametric, polar, rectangular, etc), factors, expands, etc. much more) If you dont have one and you are in any higher level math course/ engineering courses... GET ONE!!!

Cons: Unfortunately wally world sells them much cheaper then new egg and doesnt charge for shipping.

Other Thoughts: MAKE SURE TO TEST BATTERIES... If you can use this calculator on your test and your batteries go out... your outta luck!!!

Rating + 4 Excellent


Pros: Plenty of applications available for it from TI, plenty more from ticalc.org, comes with EE apps, and software available to transfer notes/docs/chm/xls/etc.

Cons: Low memory considering the wealth of applications that could be run from it. You'll have to pick and choose.

Other Thoughts: So far it's been a great calculator, although it's graphing speed isn't anything special.
