The death of calculator market?

[rawi]

Hi,

interest can be tracked with Google trends which reports how the searches for certain terms develop. If I put in "calculator" I get the following picture for the last 5 years and the world:

This shows a stable if not increasing interest.

Same picture for the US or using "Taschenrechner" for Germany.

Unfortunately the curve for the HP prime is going down:

So there seems to be a constant interest in the general topic and no signs of death being near by, but HP seems to lose.

Best
