differences in casio 991ES and 991CW calculators

[cjsuk]

Just fell over this on my quarterly forum check.

The new CW ones are the devil's butthole when it comes to calculators. Absolutely despise them. The worst one is the black one with blue legend which is entirely invisible. The menus are horrible, the functions are horrible and there are a number of weird bugs when manipulating the previous answer. And they slide around all over the place and the display contrast is terrible in anything other than perfect light. Not impressed.

Someone gave them a design award for the steamer.

Alas I have just been forced to use one, an 85CW for academic reasons and buy one for my daughter for the same reason.

Urgh.

I think the redesign was really prompted by the large market of cloned 991EX and similar on the Chinese market which are chock full of nasty bugs. That is rather than a redesign to make things better for the end user...
