I have had the classpad for two years now with minimal issues, however on Monday my classpad froze completely, I couldn't even turn it off. I thought it would turn off after awhile so I put it back and left it. The next morning, it had drained the batteries completely. Batteries which I had replaced in it only a week before/

The CASIO fx-CP400 (I'll call it the Classpad) is the best modern CAS capable calculator on the market. It beats the main competition (the TI-Nspire CX CAS and HP-Prime) in a number of ways: 1. It uses regular batteries. The Nspire and Prime use rechargeable lithium batteries that aren't easily replaceable. They require recharging via a USB port which is kind of a pain if your battery dies in the middle of a test and you don't have an outlet nearby. With the Classpad, just pop in some spare AAA batteries and you're good to go. If you want to use rechargeable NiMH batteries you can still do that. 2. It has a HUGE touchscreen and a pen stylus. The Prime has a touchscreen but it is smaller and no stylus, and the Nspire doesn't even have a touchscreen (it has a clunky ... MoreThe CASIO fx-CP400 (I'll call it the Classpad) is the best modern CAS capable calculator on the market.

The Prime has a touchscreen but it is smaller and no stylus, and the Nspire doesn't even have a touchscreen (it has a clunky mousepad/button combo). It's so big you can split the screen in half and do graphing and calculations at the same time. 3. It is cheaper. Street price for the Classpad is lower than the Nspire CX CAS and Prime. In addition to the ways that it beats both of it's competitors, it is at least as good in a number of other ways: large math function library, good computer algebra system (CAS), good programming ability, easy interface. I firmly believe this is the best modern calculator for students. The only real drawback is that Casio is less popular than TI, so you would get more support from your friends with an Nspire. But I think that if you spend some time with the Classpad you'll figure it out and won't need help for most of the things a student would be doing. Note: This isn't the best calculator for everyone. Some students aren't allowed to have a CAS, and there is no non-CAS option for the Classpad like there is for the Nspire. Also, some advanced users (i.e. not students) don't need or want a fancy screen, in that case the TI-89 or HP-50G are both good choices that offer a solid CAS at a lower price.

Well, I am a Civil Engineer and have very much all of the newest advanced calcs. But Casio Classpad eclipses all of the together. Thanks

I had always regarded Texas Instruments as the Rolls Royce of calculators since the 1970s when TI produced the ground breaking TI 59, which was highly prized among engineers and other assorted maths types. So I had been using TI calculators as they evolved over the decades into the current, scarily powerful, TI nspire CAS CX. With its illuminated color display, the TI nspire seemed to me eminently superior to the Classpad 330 and its feeble LCD display, which was so difficult to read under just about all lighting conditions, and I didnt know why anyone would be bothering with the Classpad. Then the Classpad II, also known as the Classpad II FX CP400 or Classpad 400, appeared on the scene, and completely bowled me over. The Classpad and the TI are just about ... MoreI had always regarded Texas Instruments as the Rolls Royce of calculators since the 1970s when TI produced the ground breaking TI 59, which was highly prized among engineers and other assorted maths types.

With its illuminated color display, the TI nspire seemed to me eminently superior to the Classpad 330 and its feeble LCD display, which was so difficult to read under just about all lighting conditions, and I didnt know why anyone would be bothering with the Classpad. Then the Classpad II, also known as the Classpad II FX CP400 or Classpad 400, appeared on the scene, and completely bowled me over. The Classpad and the TI are just about equivalent in capabilities, with the Computer Algebra System (CAS)and graphing functions being pretty much the same on both models. Where the Classpad is the clear winner (in my opinion) is the larger display (twice the area), and the touch screen, which lets you swipe over a calculation or function or formula and drag it to a different position and context on the screen. The TI has a touch-sensitive pad, which you can use to move a mouse pointer on the screen, but it is still a mainly keyboard based sytem, compared to which the Classpads touch screen is just superior. You may be wondering why Im going on about the TI when this is supposed to be a review of the Classpad. So am I. I guess Im just setting out my experience for someone who may be wondering which one to buy. I couldnt possibly describe all the capabilities of the Classpad it would take a whole book. A nice feature is the rotate icon at the bottom of the screen, which allows you to rotate the screen from portrait to landscape orientation, handy when an expression is too long to display on the screen when in portrait mode. Pressing the keyboard key (the actual key on the minimalist physical keypad) brings up a smorgasboard of diffent on-screen keyboards each with its own set of functions (trig, maths, characters etc). The physical keyboard has the most often used keys available (x, y, + = etc including the comma I was surprised how often I found myself using the comma, and it seems a lot of thought went in to deciding what keys to put on the physical key pad). I havent mentioned the Classpads stylus, the little plastic pen that you use for tapping and dragging on the touch screen and which a lot of people end up losing. You can equally well use the top end of you biro or pencil, and most times your finger works just fine.Anyway, as I said I couldnt possibly review the myriad features and functions of this miracle of engineering. I highly recommend the demo tutes on line at Classpad II Help Series. The demonstrator moves along fairly quickly but just pause it with a mouse-click, give yourself time to catch up, and resume playing. He probably needs to move along because theres so much to cover. (Actually you get to sort of like him after a while, but hes a bit of a no-nonsense type of guy). The tutorial index is divided into different levels, from basic to more esoteric functions. It would take hours to work through all the tutorials, and if youre new you should repeat a lot of them, otherwise you wouldnt possibly remember everything. Its all there though, whatever you want youll find trig, financial, statistical, graphing, algebra, calculus, probability, spreadsheets, etc even the list of topics is too long to cover here. A useless foot note but one I find sort of interesting. Most people probably wont be in the slightest interested in this. You can upload pictures to your calculator screen, but they have to be in Casios own picture file format (so you cant upload jpeg or bmp images for example). Casios filename extension for their picture files is .c2p (classpad to picture presumably) and Casio provide what they call their Picture Conversion Engine software to convert your images on your PC to the .c2p format required for uploading to the calculator. Except they dont provide it. They refuse to provide it to ordinary members of the public, and they dont even bother to explain why they dont provide it. (Maybe theres stuff they dont want school kids loading on their calculators? Dont know. But if you want to put a photo of your favourite person or cat on your calculator screen you cant. You can however do this on the TI Nspire.) Anyway, final verdict: 100 out of 10 for this calculator in my opinion.
Great calculator, incorporating new screen technology, such as a large color touch screen. Eyes were made for color processing, so a low resolution tochless screen doesn't cut it anymore. Funcionality wise, is capable of all the engineering calculation I require, All in all, very happy with this product.
I've had this calculator for around 3 years now for school, and it's still working but sometimes it gets extremely slow. Once I was in an exam and was solving a trigonometry question and it got stuck for like at least 5 minutes, and I couldn't even solve other equations in the meantime.
This is a great calculator that has an excellent array of features. I highly recommend this for any student or business person.
I bought this calculator, unpacked it, inserted batteries and it wouldn't turn on. Tried three sets of batteries. Had to return it the same day that I bought it.
Up to my 3rd classpad in 2 years as they stop working. One brand new and one second hand one have died on me. Have to keep buying them for school
due to the hefty price tag of this product, I expected it to last longer than just over a year. bought it for school, and completely out of the blue, the calculator broke. There was no prior damage (it only went to and from school) and I expected more from such an expensive calculator from such a reputable brand. I can't afford another one and now have to borrow one for my classes. do not recommend.
