Casio Prizm keyboard

[Chasfield]

I like my ten year old Casio FX 9860G. The keyboard is reliable, display contrast perfect and it sits on a USB cable acting like a mass storage device. All USB enabled calculators should do this. Many don't and seem to be stuck in a weird, Kermit-fixated past, with some kind of drag and drop functionality laid on the top to paper over the cracks.

I wouldn't mind having a Casio Prizm but in the UK they were for a long time punishingly expensive, with a price point set to guarantee almost no sales whatsoever. 100 GBP is the mark at the moment, which is a bit better than it was when I was considering one.

I did buy a Prime, which, at the time, was much more fairly priced in the UK (kudos to HP). Its speed and pinch-to-zoom functionality are great.
