CASIO fx-991CW

[Dands]

I am an electrical engineer and the 991EX was my go to calculator during school. Passed both FE and PE exams using it as well. Here's why I think the 991CW was a HUGE fail for Casio given that they are still marketing this calculators to engineers:

- They got rid of the ANGLE key(shift option): if you are an electrical engineer and rely on phasor notation, Casio screwed you. The easily accessible angle key is gone. To enter a phasor you will need to go through a series of menu options. It is also hard to convert between rectangular and polar forms, more menu options. Huge miss.

- They got rid of the ENG key. The 991EX made it easy to toggle between 10ˆx powers (both positive and negative!) using the ENG key. It's GONE.

- Forget the amazing S<=>D key. Now you have to use this terrible FORMAT key and go through a series of options to switch between standard and fraction notation. You will have to do this EVERY TIME. What were they thinking?!

- Plus all the weird key placements - ANS is not next to EXE (or =). STORE and M+ keys gone....total miss.

I returned mine and will buy an extra 991EX as a backup during the coming zombie apocalypse....if you're studying to be an engineer, or are already practicing the profession, stay away of this CW model. Casio, hope you read this and release a Version 2 as soon as possible. A super clean keyboard is NOT always the best option.

Thanks
