Eventually I plan to install KhiCAS on it, and see if I like it better, but as far as I know it's the 2nd best modern calculator out there, but this is subjective as I have seen people who love the document-like setup and the menus and cleaner looks vs a more conventional look.This article contains content that is written like an advertisement.
I'd recommend it over the TI 84 Plus CE, but not ovet the HP Prime.
The battery life is good, but I honestly wish I could also use conventional batteries like the older TI Nspire (non CX) did, to ensure this calculator will last me a lifetime (I still have both an HP 50G and a TI 89 Titanium purchased in 20 I believe, both working great).Ĭonsidering the TI 84 Plus CE is at this price range, I think the price of this calculator is very competitive. I also have the HP Prime, it's direct competitor in terms of features, and so far I enjoy the Prime a bit better but I like the vector handling of the CX II better than the Prime, so I have both at my desk. The calculator is very fast and responsive, but the touchpad is slightly annoying to use. I am not the biggest fan of the document-like approach for the calculator, and I'd rather have some of the more used functions with an assigned button rather than accessing them with menus (even trig functions) rather than the dedicated keypads with all letters. I am a professional, not a student, and I have similar calculators. The calculator feels light which I am not a big fan of, but I generally baby my calculators so it won't be an issue. Great calculator, it arrived quickly and the packaging was not one of those nearly impossible to open so first impressions were good. However, be warned that the touchpad irritably exists and the battery life may be too short. So, overall, it's a fantastic calculator. I have to recharge the device every day basically, which is much less than the months I got out of my TI 89 Titanium. I wish there were a way to disable the touchpad.Īlthough the battery is conveniently rechargeable, if you plan on using this for hours per session, the battery will not last long. This isn't very pleasant, especially if you plan to use this for hours. There have been times when I would quickly click on the arrow keys to have the touchpad functionality enabled and cause an incorrect selection. While the touchpad is "modern", it is straightforward to accidentally swipe your finger on the pad and select the wrong action. However, I have an issue with its touchpad. Also, it graphs functions a lot quicker than any other Texas Instrument calculator and looks really good with its multi-colour display. This calculator is easier to operate, especially when it comes to graphing functions. But to be honest, I don't mind it because it organizes everything into a little menu. Eventually, I chose this calculator despite its higher cost since I was already comfortable with the key layout (from previous Texas Instrument devices) and overall functionality.įor most of my life, I've used the TI 89 Titanium, and although the CX II is easy to learn, there was a learning curve as the function keys are all moved to the menu button. Having owned the TI 84 and then the TI 89 Titanium, this calculator was one of two options I was considering when upgrading. It has been about two weeks since I purchased this calculator, and since then, I have used this device daily for about two to three hours each.
